Frequently asked questions (FAQ) about MediaWiki. If your question is neither answered here nor in the old meta FAQ, then please ask for help in our IRC channel or in the Support desk. This FAQ is slowly replacing the version at meta. If the answer you are looking for is not found below, try looking there as well.  Languages: English • Català • Deutsch • Español • Français • ગુજરાતી • עברית • Italiano • 日本語 • 한국어 • മലയാളം • Occitan • Polski • Português • Русский • 中文(简体)Contents [hide]
Installation and configuration Where do I download MediaWiki? Click here to download the latest stable release of MediaWiki. Files are supplied in a .tar.gz archive. MediaWiki can also be obtained direct from our Subversion repository. How do I install MediaWiki? Installing MediaWiki takes between 10 and 30 minutes, and involves uploading/copying files, and running the installer script to configure the software - see Installation. Full instructions can be found in the INSTALL file supplied in the distribution archive. How do I install MediaWiki using a package? Many Linux distributions provide MediaWiki in a packaged format for that distribution. The MediaWiki development team refers you to your Linux distribution for assistance with installing, configuring or using them. The individual communities & companies who maintain such packages should provide installation instructions. Can I install more than one wiki on a server using MediaWiki? It is possible to install more than one wiki on a server provided that:
For information on setting up a wiki family, see Manual:Wiki family. For information on an alternative way of setting up more than one wiki using the same server, database and source, see Steve Rumberg's (archived version) excellent expose and additional comments from users. Does MediaWiki work with safe_mode enabled? Yes, but only to a limited degree. See Safe mode. Does MediaWiki require shell access? Shell access (SSH access) is not required for installing MediaWiki, but it is highly recommended. Without shell access, it may even be difficult for you to get a backup of your wiki, or to upgrade to a new version. Some maintenance tasks will not be possible at all without shell access. How do I install extensions? See Manual:Extensions for information about installing extensions, as well as writing them. See the Extension Matrix and the Category:Extensions to find existing extensions. How do I add extra namespaces? To add a namespace, modify your LocalSettings.php file, and add namespaces via $wgExtraNamespaces. You can add the following code to add a "Portal" namespace, and its corresponding discussion namespace: $wgExtraNamespaces = array(100 => "Portal", 101 => "Portal_talk");  Note: Be sure to add underscores instead of spaces, such as in Portal_talk. Otherwise, the namespace will not be declared properly!How do I enable uploading? File uploads are an often-used feature of MediaWiki, but are disabled by default in all current release versions. To enable them, first make the upload directory (default images) writable by the web server (chmod 777 or allow the Apache user to write to it, etc.) then set $wgEnableUploads to true in LocalSettings.php (i.e. "$wgEnableUploads = true;"). See Manual:Configuring file uploads for more information. How do I enable embedded math formulas? MediaWiki allows embedded math formulas via a helper program called texvc that uses LaTeX to render the formulas. See Manual:Math for setup instructions. How do I purge a cached page? To purge a cached page, such as when making changes to the navigation bar, add &action=purge to the end of the page's dynamic URL. e.g. http://www.mediawiki.org/w/index.php...e&action=purge or ?action=purge to the end of the page's short form URL: e.g. http://www.mediawiki.org/wiki/Main_Page?action=purge See also: Manual  urge, Manualarameters to index.phpHow do I allow uploading of additional formats? MediaWiki requires that allowed file upload formats are specified using the $wgFileExtensions configuration directive. Usually this directive is situated in LocalSettings.php in the root of your MediaWiki installation. For example, to allow uploading of PDF files, add the following to LocalSettings.php: $wgFileExtensions[] = 'pdf'; Note: The syntax is different to allow uploading of more than one type of file. To do so, use an array as in the example below which will allow uploading of png, gif, jpg, jpeg, pdf, and txt files. $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'pdf', 'txt' ); See Manual:Configuring file uploads for more information."File is corrupt or has an invalid extension" Some users have reported that after adding a file format to the allowed extensions list, an error is encountered. The text of the error is similar to the following: The file is corrupt or has an incorrect extension. Please check the file and upload again. Possible solutions:
Initial user was not created by installer Sometimes, the installer fails to create the default user, or the user table is lost for some reason. There are a couple of options for solving this: maintenance/createAndPromote.php
Alter the database
How do I reset a password? You can use the maintenance/changePassword.php maintenance script to reset a user's password. You have to run the script from the command line. In other words, log into the server where your wiki is installed, then open a command prompt. Go to the installation directory, then go to the maintenance subdirectory. Run the following command: php changePassword.php --user=someuser --password=somepass Where obviously "somepass" is changed to the password you want to set and "someuser" is changed to the user name as it is listed in the table "user". You can also use the old way, by modifying the database directly. Assuming that $wgPasswordSalt is set to true (the default), you can use the following SQL query for MySQL: UPDATE user SET user_password = MD5(CONCAT(user_id, '-', Where obviously "somepass" is changed to the password you want to set and "someuser" is changed to the user name as it is listed in the table "user".MD5('somepass'))) WHERE user_name = 'someuser'; Note: The user_id in the CONCAT string is a column name and is not meant to be replaced with 'someuser' Note: If you obtain a 'dbname.user table does not exist' error, please check the LocalSettings.php file, and double-check the value for the $wgDBprefix variable. If that variable is not empty, try repeating the command, replacing $wgDBPrefix_user instead of user in the UPDATE clause of the SQL statement.If using PostGreSQL, use this query instead: UPDATE mwuser SET user_password = You can also try the Password Reset extension.md5(user_id || '-' || md5('somepass')) WHERE user_name='someuser'; How can I create interwiki links in my wiki? DB expert answer If the external wiki you are interested in is Wikipedia, and you wish to use the prefix "wp" to link to it (the prefix "wikipedia" is the default interwiki prefix for Wikipedia, see Help:Interwiki linking for other defaults), run this SQL statement to modify the interwiki table in your database: INSERT INTO interwiki (iw_prefix, iw_url, iw_local, iw_trans) VALUES ('wp', 'http://en.wikipedia.org/wiki/$1', '0', '0'); The $1 indicates the article name on the external wiki.Typical user answer In a graphical SQL program (i.e. PhpMyAdmin), go to the interwiki table. Choose the option to insert (a row). In the iw_prefix field, enter your desired interwiki prefix. In the iw_url field, enter the Base URL of the external wiki plus the text "$1" as mentioned in the DB Expert Answer above. iw_local and iw_trans have default values of zero (0). You may leave them as zero. For more information, see Help:Interwiki linking Easy answer Install the Special:Interwiki extension. You can then add and remove interwiki entries through the Special:Interwiki special page. How do I make my base URLs shorter? (i.e. /wiki/Article_Name as opposed to /w/index.php?title=Article_Name) See Manual:Short URL. Is downloading and using all of MediaWiki.org free? Yes, it is free in the sense of Free software. See Project:Copyrights for licensing issues regarding the written content of this site. How do I administrate/manage user rights? See Manual:User rights and Manual:User rights management for general information. See Manual reventing access for methods and strategies for restricting access.How do I stop anonymous users from editing any page?

See also Manual:Upgrading. How hard is it to upgrade? If the only file you have modified is LocalSettings.php, and you are upgrading from 1.5 or later, the process is very simple. The amount of human work involved is only a few minutes. The database schema changes will take an amount of time proportional to the size of your database -- potentially hours for wikis with millions of pages, but for a more typical size of a few thousand pages, it is usually done in seconds. Minor upgrades, within the same major version, say from 1.13.0 to 1.13.1, do not require any schema changes at all. You can just update the files. Upgrading from 1.4 or earlier is potentially complicated because support for character sets other than UTF-8 was dropped, and the schema for storing bulk text changed. Please read the relevant section in the UPGRADE file. Upgrading becomes difficult if you have modified our source code, and you don't want your changes to be overwritten. Tools such as diff and patch may be useful. There is also potential for trouble if you are using unmaintained extensions. Upgrade your extensions at the same time as you upgrade MediaWiki. How do I upgrade from a really old version? In one step, or in several steps? In one step, from your old version to the latest stable version. The vast majority of reports, as well as automated testing, indicate that doing it in one step works just fine. If you have trouble believing this, read this mailing list post. Should I back up first? Short answer: yes. Long answer: it depends on a) how much you value your data, b) how hard it is to create a backup and c) how confident you are with MySQL maintenance and administration. An upgrade failure may leave your database in an inconsistent state, in between two versions. It may move an important table to a temporary name and then fail before it recreates the table correctly. It may change a field definition to an incorrect data type. It is very rare for an upgrade to cause irreversible data loss. More often, data corruption occurs which can be reversed by a skilled administrator. Recovery is often complex. Volunteers on the support forums are unlikely to be impressed if you neglect to make a backup and then need help to recover from upgrade-related corruption. A better outcome is if you can revert to your backup, and then report the bug in the upgrade process which caused the corruption. Can I keep my LocalSettings.php? Yes, but you may have to make some minor changes. The format of LocalSettings.php is largely backwards compatible. Changes which break LocalSettings.php compatibility will be documented in the "configuration changes" section of the release notes. Can my wiki stay online while it is upgrading? Yes. If you are upgrading between minor releases, all you need to do is update the source files. If you are upgrading between major releases, the preferred procedure is as follows: 1. Unpack the new version of MediaWiki into a new directory 2. Prepare the new directory with a valid LocalSettings.php and copy any extensions over. 3. Enable read-only mode in LocalSettings.php of the old directory $wgReadOnly = 'Upgrading to MediaWiki 1.14.0'; 4. Run the upgrade script in the new directory. 5. Swap the old directory and the new directory. Changing the interface How do I change the logo? The logo that appears in the top left of each page is determined by the $wgLogo configuration line in the LocalSettings.php file. There are two ways to change the logo: Upload a picture with your wiki and use that address. This allows the photo to be replaced easily, so you may want to protect the page if you use this method. Then add the $wgLogo line to LocalSettings.php, for example: $wgLogo = 'http://www.example.com/wiki/images/6/62/photoname.jpg'; Or upload an image to your server by other means (such as FTP). Add the $wgLogo line to LocalSettings.php, for example: $wgLogo = "{$wgScriptPath}/photoname.jpg"; In this example, the photo is in the same folder as the LocalSettings.php file. It is generally a good idea to place this at the end of LocalSettings.php, especially if you are using a variable such as $wgStylePath or $wgUploadPath.  Caution: Do not simply overwrite the default logo installed with MediaWiki (/skins/common/images/wiki.png); this file will be overwritten when you upgrade.Tip: The logo image should be 135 x 135 pixels. How do I edit the wiki's CSS? You shouldn't edit the CSS files (such as main.css) directly, because it will make upgrading harder if you need to apply your customizations each time you upgrade the software. Instead you need to edit a wiki page called MediaWiki:Common.css if you want to apply your CSS changes for all skins, or a wiki page called MediaWiki:Monobook.css if you want to apply the customizations only for Monobook skin. The content of MediaWiki:Common.css and MediaWiki:Monobook.css pages always override the default CSS styles specified in main.css. How do I hide the left vertical navigation toolbar In other words, how do you make the main content div take up 100% of the display, hiding the logo, toolbox, navigation and search engine? To hide it permanently, put the following in MediaWiki:Common.css: #column-content { margin: 0 0 .6em 0; } To instead hide the toolbar when the user presses F11, enter this in your wiki's MediaWiki:Common.js:#content { margin: 2.8em 0 0 0; } #p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search { display:none; } #p-cactions { left: .1em; } document.onkeydown = function( e ) { if( e == null ) e = event if( testKey( e, 122 ) ) { //F11 appendCSS('#column-content {margin: 0 0 .6em 0;} #content {margin: 2.8em 0 0 0;} #p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search {display:none;} #p-cactions {left: .1em;} #footer {display:none;}'); return false; } } function testKey( e, intKeyCode ) { if( window.createPopup ) return e.keyCode == intKeyCode else return e.which == intKeyCode } How do I customize the logo in the top left corner? Can I? The logo is a portlet block without a pBody section. It is identified by the p-logo id. The background image is specified by the $wgLogo variable, which is defined in DefaultSettings.php. This location is relative to the web server root and not the system root. Redefine this in LocalSettings.php to change the image. If set wrong there will be no image on the page; check your web server error log and adjust accordingly. However the size of the p-logo will need to be big enough for the logo if it is not to be clipped. This is set in the stylesheet (main.css in Monobook), under the p-logo style, the default setting is: #p-logo { z-index: 3; position: absolute; /*needed to use z-index */ top: 0; left: 0; height: 155px; width: 12em; overflow: visible; } How do I customize the URL of the logo in the top left corner when you click it? By default, clicking the logo takes you to the main page. If you want to change which page is the main page, edit MediaWiki:Mainpage. To make the link go to any arbitrary URL, for Monobook skin, you'll need to edit MonoBook.php (in other words, you need to do a core hack) and find and replace <?php echo htmlspecialchars($this->data['nav_urls']['mainpage']['href'])?> with the URL of your choice and replace <?php $this->msg('mainpage') ?> with the desired link title. Example to link to your Root: Replace ?>href="<?php echo htmlspecialchars($this->data['nav_urls']['mainpage']['href'])?>" <?php with?>title="<?php $this->msg('mainpage') ?>"></a> ?>href="/" <?php ?>title="Root Page Name"></a> Reducing the size of the logo Note that a tag is on top of the logo so if you are trying to reduce the size of the logo's portlet you will also need to change the #p-logo a and #p-logo a:hover rules. The default setting for these is: #p-logo a, This simple customization will re-define the size of all of them at once...#p-logo a:hover { display: block; height: 200px; width: 12.2em; background-repeat: no-repeat; background-position: 35% 50% !important; text-decoration: none; } #p-logo, There is one more rule controlling the amount of space between the logo and first portlet in the side column - the padding on the top of #column-one. By default this is:#p-logo a, #p-logo a:hover { height: 75px; } #column-one { padding-top: 160px; } If you want to remove the logo completely, comment out the $wgLogo variable. Then set the column-one padding to a small value, such as 21: #column-one { padding-top: 21px; } How do I change the icon in the browser's address line (favicon)?
Tip: The favicon image should be either 16 x 16 pixels or 32 x 32 pixels. Rewrite Rule If you are using a rewrite rule in .htaccess to remove "index.php" from the URL, you will also need to add an exception for .ico files. Simply add the following rule to your .htaccess: RewriteRule .*\.ico$ - [L] This rule must appear before the index.php rule. Case sensitivity When uploading the favicon file, be sure the filename is in lowercase. (That is, "favicon.ico", not "Favicon.ico".) A lot of servers (e.g., those on UNIX-like operating systems) will not be able to find the file unless its name is in lowercase. How do I customize the navigation bar? The contents of the navigation bar which appears to the left of each page using the Monobook skin are determined by the MediaWiki:Sidebar page there on your wiki. For information on customising these, please see Manual:Navigation bar. How do I put a text message (sitenotice) on every page? Put a text in the MediaWiki:Sitenotice page. It will be displayed on top of every article page. How do I change which page is the main page? By default, MediaWiki looks for a page with the title Main Page and serves this as the default page. This can be changed by altering the contents of MediaWiki:Mainpage to point to a different title. If this does not change the 'Main Page' link included on the sidebar at install time, edit MediaWiki:Sidebar. How do I change the Main Page title? Starting from 1.14, you can edit the system message MediaWiki agetitle-view-mainpage to change <title> of the main page. [1].How do I hide the main page title? MediaWiki does not have a built-in option to hide the main page title (see bug 6129). Instead you must use JavaScript or CSS. MediaWiki version before 1.9, solution to hide the main page title Before MediaWiki 1.9, you have two options: Apply the patch You can manually apply the patch from r17119 to your copy of MediaWiki and use the solution for 1.9. First replace or add the lines in three files in the correct place as r17119 did:
JavaScript solution The following JavaScript may or may not work for your wiki (replace "Main Page" with the name of your main page if it differs). Add the code to your wiki's MediaWiki:Common.js or MediaWiki:Monobook.js (Monobook.js for older wikis, Common.js for newer wikis): var isMainPage = (document.title.substr(0, document.title.lastIndexOf(" - ")) == "Main Page"); var isDiff = (document.location.search && (document.location.search.indexOf("diff=") != -1 || document.location.search.indexOf("oldid=") != -1 ) ); if( isMainPage && !isDiff ) { document.write('<style type="text/css">/*<![CDATA[*/ h1.firstHeading { display: none !important; } /*]]>*/</style>'); } MediaWiki version 1.9+, solution to hide the main page title In 1.9 and above (or with the modified files above), you can use CSS to hide the main page title. Add the following to the MediaWiki:Monobook.css (if you're using Monobook; otherwise add this to MediaWiki:Common.css to have it applied to all skins) on your wiki: body.page-Main_Page h1.firstHeading { display:none; } Alternatively, you can replace "Main_Page" with another name, but with spaces replaced by underscores _ .Troubleshooting If this doesn't work, look at the HTML source code to find the correct class to replace "page-Main_Page" with: <body class="mediawiki ns-0 ltr page-Some_title"> If no such class exists, then you cannot use this feature. You may be using a custom or outdated skin.Another option is to #REDIRECT from Main_Page to Our_Main_Page. See also Wikipedia:Main Page alternatives. How can I hide the table of contents? The table of contents (TOC) is automatically shown once there are four or more headings in the article. The are multiple ways to hide it. For one pagePlace the magic word __NOTOC__ into the page markup.For all pagesAdd the following rule to MediaWiki:Common.css: .toc, #toc { display: none; } However, this is not the best solution, because the table of contents will be hidden even in those pages in which we want it to be displayed, by using the magic words __FORCETOC__ or __TOC__. A simpler and more efficient alternative is to edit the file /includes/parser/Parser.php, altering in line 3427 the limit of 4 headings: (($numMatches >= 4) || $this->mForceTocPosition); to a higher value (e.g. 10). This way the table of contents will only be displayed in pages with 10 or more headings, OR in pages which contain one of the magic words __FORCETOC__ or __TOC__.Per userUsers can also opt to have the table of contents hidden. This is a user preference, set in Specialreferences. How do I change the interface text? Interface text is altered using the MediaWiki namespace. For each deviation from the default in the site language there is a page MediaWiki:Englishmessagename, and for each deviation from the default in each other language a page MediaWiki:Englishmessagename/languagecode. (Since release 1.9 there are no pages for messages equal to the default.). On creation of a page the edit box autofills with the default. When creating a page to override the default it is useful to first save the default version, to allow diffs with it. See also Manual:System message.
How do I change the interface language? To change the default interface language, alter the value of $wgLanguageCode in LocalSettings.php, e.g. $wgLanguageCode = "fr"; How can I prevent editing by anonymous users? The recommended method is by changing the value of the $wgGroupPermissions configuration option. Edit LocalSettings.php and add the line: $wgGroupPermissions['*']['edit'] = false; For more information on using this option, see the Preventing access page and Manual:User rights.How do I remove the article/edit etc tabs for users who are not logged in? Edit [[MediaWiki:Monobook.css]] on your wiki, and add this: #ca-edit { display: none; } See the page source for the various #ca-* ids used in the content tabs. Note: this will only work for MonoBook (the default skin), and doesn't actually stop people editing. How do I add/remove tabs throughout my wiki? For example, to remove the talk tab and then add a tab that always goes to the main page you would save this code in extensions/AR-Tabs.php: <?php and then addif( !defined( 'MEDIAWIKI' ) ){ die( "This is not a valid entry point.\n" ); } $wgHooks['SkinTemplateContentActions'][] = 'replaceTabs'; function replaceTabs( $content_actions ) { unset( $content_actions['talk'] ); // only this to remove an action $maintitle = Title::newFromText( wfMsgForContent( 'mainpage' ) ); $main_action['main'] = array( 'class' => false or 'selected', // if the tab should be highlighted 'text' => wfMsg( 'sitetitle' ), // what the tab says 'href' => $maintitle->getFullURL(), // where it links to ); $content_actions = array_merge( $main_action, $content_actions ); // add a new action return true; } require_once("extensions/AR-Tabs.php"); to the bottom of LocalSettings.phpHow do I remove a tab on only one page? This solution works in MediaWiki version 1.9 and above. In MediaWiki version 1.8 or below, first apply the above patch. For example, to remove the Discussion (talk) page tab from the Main Page, on the MediaWiki:Monobook.css page add: .page-Main_Page #ca-talk { display: none !important; } To modify MediaWiki:Monobook.css you must have administrative privileges.How do I remove a tab on all pages This solution works in MediaWiki version 1.9 and above. In MediaWiki version 1.8 or below, first apply the above patch. For example, to remove the Discussion (talk) page tab on all wikipages, on the MediaWiki:Monobook.css page add: #ca-talk { display:none!important; } Other tabs to remove are #ca-history and #ca-viewsource. To modify MediaWiki:Monobook.css you must have administrative privileges.How do I hide the section edit links for users who are not logged in?
Replace #ca-edit with #ca-viewseource if you disabled editing for anonymous users. Use .editsection for older MW versions. If you want to hide the links for all users including logged in users, instead edit monobook/main.css ('not recommended!) and add: #ca-edit { display: none; } Also see How can I prevent editing by anonymous users? How do I remove the "Talk for this IP" link at the top right when $wgDisableAnonTalk is true? Set $wgShowIPinHeader to false. How do I remove the "Create an Account or Login" link at the top right of the screen? In Monobook.php change this statement: foreach($this->data['personal_urls'] as $key => $item) { to: foreach($this->data['personal_urls'] as $key => $item) if($this->data['loggedin']==1) { How do I change the footer? To add or remove items from the footer on your MediaWiki page, you must edit the skin. For example: if you go in to MonoBook.php (located by default in the skins folder) you will find the following code: $footerlinks = array( In the above you can simply add and remove items from the footer that you wish to appear in your footer. Remember the changes may not appear immediately because of MediaWiki caches.'lastmod', 'viewcount', 'numberofwatchingusers', 'credits', 'copyright', 'privacy', 'about', 'disclaimer', 'tagline', ); You can also customize the individual items by modifying certain pages or parameters:
Line breaks in footer Edit MediaWiki:Copyright and add <br /> tag before and after the actual text of the message. How can I edit / remove the Powered by MediaWiki image in the footer? You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css: #f-poweredbyico { display: none; } If you want to remove it completely, you could alter /skins/MonoBook.php, which contains the following code that makes the Powered by MediaWiki image appear in the footer: <?php If you would like to remove this image completely, or edit the image, you must locate and edit poweredbyico. It is located in skins/common/images/ and the image is called poweredby_mediawiki_88x31.png.if($this->data['poweredbyico']) { ?> <div id="f-poweredbyico"><?php $this->html('poweredbyico') ?></div> If you're happy with the logo (or not) and simply want to change the destination link, the code is in getPoweredBy() function of includes\Skin.php. Just change the line $img = '<a href="http://www.mediawiki.org/"><img src="'.$url.'" alt="Powered by MediaWiki" /></a>'; to whatever. How can I change what the <title> of each page is? Where do I make changes? Most of the text that you want to change, can be found in the namespace of MediaWiki. In order to change titles, texts, announcements and the such, go to Special:Allmessages, where you will see the text associated with the pages you wish to change. You need to log in as an administrator (like the one you made when you installed) to edit the protected entries in the MediaWiki namespace. If you want to change the title in your browser, you need to edit MediaWiki agetitle. Go there and edit it just like you would any other page in your wiki.In recent versions of MediaWiki, MediaWiki agetitle is $1 - {{SITENAME}} by default. If {{SITENAME}} is producing the wrong text for you, you need to set $wgSitename in your LocalSettings.php.If $wgSitename is correct in LocalSettings.php but {{SITENAME}} is still wrong, it may be that you're using a user-contributed language file which incorrectly sets $wgSitename to a transliteration of "Wikipedia". Edit the language file to correct this. For example, the Hebrew language file is at languages/LanguageHe.php in your wiki directory. Don't forget to clear your browser cache after you fix it. How do I make external links open in a new window? See Opening external links in a new window. How can I suppress MediaWiki from formatting URLs, tags, etc? Put "<nowiki>" tags around the URL or tag. Example: svn co <nowiki>http://svn.example.com/myproject/</nowiki> produces: svn co http://svn.example.com/myproject/ How can I force users to preview before they save? See Manual:Force preview and Extension:ForcePreview. How do I add more buttons on the edit page? For adding more toolbar buttons above the edit field, you can use JavaScript code to register them in mwCustomEditButtons in your MediaWiki:Common.js. For example, a button for large text: var button = { "imageFile": "images/5/56/Button_big.png", // image to be shown on the button (may be a full URL too), 22x22 pixels "speedTip": "big text", // text shown in a tooltip when hovering the mouse over the button "tagOpen": "<big>", // the text to use to mark the beginning of the block "tagClose": "</big>", // the text to use to mark the end of the block (if any) "sampleText": "big text" // the sample text to place inside the block }; mwCustomEditButtons.push(button); How can I get more special characters or tags clickable on the edit page? For adding more selectable special characters, etc, below the edit field, see Extension:CharInsert. Basic usage How do I edit a page? To edit a page, simply click the edit link that appears on each page. Using the default MonoBook skin, this is in the form of a tab at the top of the page. A form will appear, containing the existing markup. When you have finished making modifications, click the Save button to commit your changes. See also: MetaWiki: Help:Editing How do I create a new page? There are several paths to creating a new page:
See Help:Starting a new page How do I delete an old version of a page? Old versions of page data are retained in the database and can be accessed via the page history features. This is useful for reviewing changes and correcting or reverting undesirable ones, but in some cases, administrators might want to make this information unavailable, for legal reasons, or to reduce the size of the database.
Are there any editing tutorials available? There are several editing tutorials available, mostly on Wikimedia sister projects, such as Wikipedia. There are also markup references, etc. available on Meta.
How do I view the printable form of a page? MediaWiki includes stylesheets which automatically style a page appropriately when it is printed; using the print or print preview function within your browser ought to render the page in a printable form. You can also view this printable form using the printable version link in the toolbox. Wiki Importing Importing from MediaWiki XML dumps See Manual:Importing XML dumps Importing from other types of wiki software Note: The following is directly copied from old meta FAQ. It might need to be corrected. There is some documentation about importing in the UPGRADE file distributed with MediaWiki. To follow on from those, this is how at least one individual imported pages from usemod to MediaWiki: Because MediaWiki does not automatically link to CamelCase style links, you will need to add brackets [[ ]] to all your links. You can do this with the following: First, obtain ImportStage1.txt (or whatever you want to call it) from the importUseModWiki.php script ( use > to pipe the output to a file ) Second, do sed '/Importing/!s/\ [A-Z]\w*[a-z]\w*[A-Z]\w*[a-zA-Z]/\ \[\[&\]\] /g' ImportStage1.txt > ImportStage2.txt This should create proper links in place of your CamelCase links. This doesn't work so well for SubPage links - someone care to fix? Then, sed 's/upload\:\w*\.\w*/http\:\/\/aberwiki\.org\/uploads\/& /g' ImportStage2.txt > ImportStage3.txt This fixes your upload links. Change the replace text so it fills in your url such as http://www.yourwiki.org/uploads/filename You are now ready to import ImportStage3.txt into your database with a command such as mysql -u<mysqluser> -p<yourpass> <db name> < ImportStage3.txt Note: If your importUseModWiki.php outputs an XML file instead of SQL statements, this probably means you have a rather new version of MediaWiki. In such a case, you case import the XML file -- see Importing a Wikipedia database dump into MediaWiki, towards the bottom of the page ('Import XML'). Don't forget to rebuild all the tables -- that page also explains how to do that. Importing from other types of files Here are some info on importing from other types of files:
MediaWiki auto importing script Taken from wiki_import - MediaWiki auto import script: Description The script is designed to import a whole folder of files into MediaWiki, with the folder directory tree mapped as wiki category hierarchy. Features
Quick Help wiki_import.sh $ $Revision: 1.1 $ mediawiki automatic file import script Usage: wiki_import.sh [OPTIONS]... The script is designed to import a whole folder of files into mediawiki, with the folder directory tree mapped as wiki category hierarchy. The specification of the file-to-import is passed from standard input.

Customising further How can I allow use of HTML tags? See Manual:$wgRawHtml as well as Manual:$wgGroupPermissions and Manual reventing access. Caution: This can be easily abused to attack usersSee Extension:SecureHTML and Extension:HTMLets for ways to make this safer. How can I allow uploading of HTML files? See Manual:Allowing HTML Uploads. Caution: This can be easily abused to attack usersWhy...? …is the Help namespace empty? We don't currently have a clean, internationalised set of help pages under a free license. A few developers are hoping to make this possible; however, the Help namespace currently ships in a blank state. You are free to add your own help pages, copy the Public Domain help pages or copy certain of the items from Meta, e.g. the user guide or MediaWiki Handbook, these two collections being free to use under the GNU Free Documentation License. …are some of my images not showing up after an upgrade? Several users have reported that, following an upgrade or a moving of their wiki, several images fail to be shown inline. The files exist, and the image description pages show a MIME type of unknown / unknown and, in some cases, a warning about potentially dangerous files. To fix this, run the maintenance/rebuildImages.php script from the command line. This will set MIME information for each file in the database. …are all PNG files not being turned into thumbnails? After upgrading to a more recent version of PHP, it is possible a different MimeMagic.php function is being used to detect file MIME types, particularly the built-in PHP function mime_content_type, which fails to detect PNG files. Search the web for mime_content_type png for information on fixing this bug at the PHP level, possibly by editing your magic.mime file. See here for more info. …is a search for a short keyword giving no hits? By default, MediaWiki uses MyISAM's fulltext matching functionality to allow searching page content. The default settings for this mean that words of less than four characters won't be indexed, so results won't be returned for those queries. To alter this behaviour, MySQL needs to be reconfigured to index shorter terms, and MediaWiki's search index table needs to be repaired, to rebuild the indices.
…can't I download MediaWiki 1.15? MediaWiki 1.15 is in a development state at present, and has not been packaged into a general release. The code can be downloaded from Subversion if desired. …doesn't this work? It works on Wikipedia! Wikipedia and other Wikimedia web sites use the current version of the code in development; at present, this is MediaWiki 1.15alpha (r48811). Coupled with the use of several extensions, this means that functionality between these wikis and your particular setup may differ.
…do I get a 403 Forbidden error after setting permissions on my Fedora system? Fedora Core enables SELinux by default. Instructions for setting SELinux permissions for MediaWiki are available. …do I get logged out constantly? This is probably related to cookies or session data, for example a problem with PHP's session.save_path [2] setting. See Log in problems. …is it a good idea to keep user accounts? At many times you just want to remove a user account out of the wiki either because it belonged to a spammer account or you just feel like it. The appropriate choice is to block the account or rename it if needed. Here is why: Do I just remove his row from the User table? Rob Church posted the following regarding this issue on the mediawiki-l mailing list: "If the user has made edits, then removing rows from the user table cause theoretical loss of referential integrity. Now, to be honest with you, I can't think of any conditions where this would cause an actual problem; "undefined behaviour" is the phrase we use. What I'd suggest doing, to be on the safe side, is running a couple of quick updates against the database: UPDATE revision SET rev_user = 0 WHERE rev_user = <current_user_id>UPDATE archive SET ar_user = 0 WHERE ar_user = <current_user_id> What this will do is cause MediaWiki to treat the revisions as having been made anonymously when generating things like page histories, which should eliminate any problems caused by these routines attempting to check user details from other tables. If the user has caused log entries, i.e. rows in the logging table, or uploaded images, then the situation becomes trickier, as you'll have to start mopping up all the rows everywhere and it could become a bit of a mess, so if the user's done anything other than edit, I would strongly recommend just blocking them indefinitely. If the username is offensive or undesirable, then you could consider renaming it using the RenameUser extension." Anti-spam See Manual:Combating spam for an overview of anti-spam measures. Where do I get the spam blacklist from and how do I install it? The spam blacklist extension can be found in Subversion, just like all other officially supported extensions. For installation and configuration instructions, consult the README file and extension page over here. How do I use $wgSpamRegex to block more than one string? $wgSpamRegex is a powerful filter for page content. Adding multiple items to the regex, however, can be awkward. Consider this snippet: $wgSpamRegexLines[] = 'display\s*:\s*none'; This example code allows convenient addition of additional items to the regex without fiddling about each time. It also demonstrates two popular filters, which block some of the most common spam attacks.$wgSpamRegexLines[] = 'overflow\s*:\s*auto'; [...] $wgSpamRegex = '/(' . implode( '|', $wgSpamRegexLines ) . ')/i'; See also: Extension:SpamRegex Where now? I've found a bug or have a feature request. Where do I post it? Bugs and feature requests should be posted on MediaZilla, our implementation of Bugzilla. Please search the database prior to posting, to avoid creating duplicate entries.
