Wat zijn de verschillende tussen MediaWiki, Wikimedia, Wikipedia en wiki?
Deze vraag wordt vaak gesteld; zie aub voor een gedetailleerd antwoord.

Ik wil een MediaWiki instantie gebruiken voor (vul hier uw doel in). Mag dit?
MediaWiki is gratis software: dit betekent dat u het mag gebruiken voor welk doeleinde dan ook, zonder wettelijke beperkingen. Verder zijn de licentiecondities alleen van toepassing op de software zelf (niet op de inhoud die u ermee aanmaakt). Dit betekent dat, alhoewel veel wikis hun inhoud beschikbaar stellen onder een (relatief) open licentie, u niet verplicht bent om de inhoud van uw wiki op een bepaalde manier onder licentie te stellen. Natuurlijk moedigen wij, als project dat opgezet is om sites zoals Wikipedia te ondersteunen, u aan om de teksten die u schrijft onder een vrije licentie beschikbaar te stellen. U bent daar echter, om kort te zijn, niet toe verplicht.

Indien je de software wenst te wijzigen of verbeteren, ben je hiervoor -over het algemeen- gemachtigd, maar er zijn enkele beperkingen en je dient de volledige tekst van de GNU GPL versie 2 te raadplegen voor details. Omdat MediaWiki gratis beschikbaar gesteld wordt, is er geen garantie, voor zover dit toegestaan is bij wet.

Waar kan ik MediaWiki downloaden?
Klik hier om de laatste stabiele release van MediaWiki te downloaden. Bestanden worden aangeboden in een .tar.gz archiefbestand MediaWiki kan ook direct verkregen worden vanuit onze Git repository.

Hoe MediaWiki te installeren?
MediaWiki installeren duurt ongeveer 10 tot 30 minuten, en omvat het uploaden/kopiëren van bestanden, en het uitvoeren van een installatiescript om de software te configureren. Zie de, waar u ook de "minimale systeemvereisten" kunt terugvinden.

Hoe installeer ik MediaWiki door middel van een package?
Veel Linux distributies leveren MediaWiki in verpakt formaat, voor die distributie. Het MediaWiki ontwikkelteam verwijst u naar uw Linux distributie voor assistentie bij het installeren, configureren of gebruik van uw distributie. De verscheidene communities en bedrijven die zulke pakketten onderhouden, dienen u te voorzien van installatie-instructies.

Let wel: derde-partij distributies kunnen oudere versies betreffen, dus let goed op informatie met betrekking tot compatibiliteit van directions en extensies.

Kan ik meer dan één wiki op een server installeren met MediaWiki?
Het is mogelijk om meer dan één wiki op een server te installeren, mits:


 * U installeert meerdere instanties van MediaWiki (zoals met een softwarebundel zoals de Bitnami MediaWiki Stack); in verschillende mappen – één voor elke wiki.

Of


 * U een verschillende database gebruikt voor iedere wiki

Of


 * U een verschillende database-prefix gebruikt voor iedere wiki (voor Postgres kan u eenzelfde effect bereiken door verschillende schema's en gebruikers te gebruiken)

Voor informatie met betrekking tot deze twee opties, zie respectievelijk ' en '.

Voor informatie met betrekking tot het opzetten van een wiki familie (wiki farm), zie

Voor informatie over een alternatieve manier om meer dan één wiki op te zetten met dezelfde server, database en bron, zie Steve Rumberg's (gearchiveerde versie) uitstekende exposé en het extra commentaar van gebruikers.

Hoe installeer ik een bestaande wiki, zoals Wikipedia of Wiktionary?
De meest gebruikte (maar niet noodzakelijkerwijs de gemakkelijkste) methode is importeren. "'Zie Wiki importeren, hieronder voor meer informatie.

(Niet-MediaWiki-methoden, zoals Xowa en Kiwix zijn te vinden op w:Wikipedia:Database download).

Heeft MediaWiki shell toegang nodig?
Shell toegang (SSH) is niet vereist om MediaWiki te installeren, maar het is "ten zeerste aangeraden". Zonder shell toegang kan het voor u zelfs moeilijk zijn om een back-up van uw wiki te maken, of om te upgraden naar een nieuwere versie. Een aantal onderhoudstaken zijn helemaal niet mogelijk zonder shell toegang. Veel belangrijke extensies werken het best met shell toegang.

Hoe installeer ik extensies?
Zie voor informatie over het installeren en schrijven van extensies. Zie de om bestaande extensies te vinden.

Hoe voeg ik extra namespaces toe?
Zie Creating a custom namespace.

Hoe kan ik het toestaan van uploads instellen?
Bestandsuploads zijn een veelgebruikte feature van MediaWiki, maar staan standaard uit in alle huidige releaseversies. Om ze aan te zetten, maakt u eerst een upload map (standaard ) waarin de web server schrijfrechten heeft (  of geef de Apache gebruiker schrijfrechten, etc.). Daarna zet u  op  in het bestand LocalSettings.php. Als u een foutmelding failed to mkdir (kan map niet aanmaken) krijgt wanneer u een bestand probeert te uploaden, dan betekent dat dat er een probleem met de rechten is.


 * Zie ook: 

Hoe sta ik het uploaden van overige bestandsformaten toe?
MediaWiki vereist dat toegestane bestandsformaten aangeduid worden met het  configuratie commando. Normaal gesproken bevindt dit commando zich in LocalSettings.php in de hoofdmap van uw MediaWiki installatie.

Bijvoorbeeld, om het uploaden van PDF bestanden toe te staan, voeg het volgende toe aan LocalSettings.php:

Om meer dan één type toe te voegen aan de lijst van toegestane bestandsformaten, gebruik de volgende syntax

Hoe kan ik een gecachede pagina opschonen?
Om een ge-cachede pagina op te schonen, bijvoorbeeld wanneer u wijzigingen aanbrengt in de navigatiebalk, voeg  toe aan het einde van de dynamische URL van de pagina.

Bijvoorbeeld https://www.mediawiki.org/w/index.php?title=Main_Page&action=purge

Of  aan het einde van de korte URL van de pagina:

Bijvoorbeeld https://www.mediawiki.org/wiki/Main_Page?action=purge


 * Zie ook:, 

Hoe kan ik caching geheel uitzetten?
Voeg de volgende regels toe aan uw LocalSettings.php bestand:

"Bestand is corrupt of heeft een ongeldige extensie"
Sommige gebruikers hebben aangegeven dat er een fout op kan treden, nadat er een bestandsformaat toegevoegd is aan de lijst met toegestane extensies. De tekst van deze fout is als volgt:


 * "The file is corrupt or has an incorrect extension. Please check the file and upload again." ("Het bestand is corrupt of heeft een verkeerde extensie. Controleer het bestand en upload het opnieuw.")

Mogelijke oplossingen:


 * Stel de waarde van  in. Dit zou bijv. onder Unix of Linux zijn:
 * Compileer/installeer de fileinfo PHP-extensie
 * Fedora - yum install php-pecl-Fileinfo
 * Fedora - yum install php-pecl-Fileinfo

Om de voorkeur te wijzigen, voegt u het volgende toe aan uw LocalSettings.php bestand:

Om de standaard namespaces voor een zoekopdracht te wijzigen, in alle versies van MediaWiki, vult u in LocalSettings.php in met een array waarin namespace indices gemapped worden op boolean waarden. Bijvoorbeeld, om te zoeken in de "main" namespace en de "category" namespace, gebruik:

In sommige gevallen wilt u, nadat u een standaard gebruikersvoorkeur wijzigt, mogelijk ook de gebruikersvoorkeuren van alle bestaande gebruikers wijzigen.

Zo ja, gebruik het userOptions.php script in de Maintenance ("Onderhoud") map. Gebruik eerst de "--dry" optie, kijk naar het resultaat, en werk van daaruit verder. (--dry schrijft niet naar de database)

php userOptions.php --dry --nowarn hideminor --old 0 --new 1

Maak ook altijd een back-up van uw database voordat u dit soort wijzigingen uitvoert (dit hoeft niet als u alleen maar --dry gebruikt).

Is het mogelijk om mijn wiki naar een andere machine te verplaatsen?
Ja. Waarschijnlijk wel. In feite maakt u een back-up van uw oude installatie, en "herstelt" deze dan naar de nieuwe machine. Tenslotte zal u aanvullende wijzigingen moeten maken in de wiki configuratie, zodat alles naar de nieuwe locatie wijst.

Hoe verplaats ik mijn wiki naar een andere server?
Volg de instructies van Handleiding:Een wiki verplaatsen.

Hoe wijzig ik het logo?
Het logo dat linksboven op elke pagina verschijnt wordt bepaald door de configuratieregel in het -bestand.

Er zijn twee manieren om het logo te wijzigen:


 * 1) Upload een afbeelding naar uw wiki via de normale uploadinterface. Hierdoor kan het logo gemakkelijk worden vervangen. Het kan hierbij handig zijn om de pagina te beveiligen als je deze methode gebruikt.
 * Voeg dan de $wgLogo regel toe aan LocalSettings.php, bijvoorbeeld:
 * 1) Upload de afbeelding naar uw server op een andere manier (zoals FTP).
 * Voeg dan de $wgLogo regel toe aan LocalSettings.php, bijvoorbeeld:
 * (In this example, the image is in the same folder as the LocalSettings.php file.)
 * (In this example, the image is in the same folder as the LocalSettings.php file.)
 * (In this example, the image is in the same folder as the LocalSettings.php file.)

If you want to change the logo in only specific pages, override #p-logo css's background-image property or use third party extension like.

Hoe bewerk ik de CSS van de wiki?
You shouldn't edit the CSS files (such as common.less) 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:Vector.css if you want to apply the customizations only for the Vector skin.

The content of the MediaWiki:Common.css and MediaWiki:Vector.css pages always overrides the default CSS styles specified in the skin files.

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, copy and paste the following into the MediaWiki:Common.css page:

To instead hide the toolbar when the user presses F11, enter this in your wiki's MediaWiki:Common.js:

How do I hide the categories at the bottom of each page?
You can hide display of the categories on each page by modifying your MediaWiki:Common.css and adding:

Can I customize the logo in the top left corner? If so, how?
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 variable, which is defined in. This location is relative to the web server root and not the system root. Redefine this in 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:

Note, if you are using a different sized logo, and want to change the CSS, please do not modify any of the core MediaWiki stylesheets. Instead add to the on-wiki css page (MediaWiki:Monobook.css for monobook, MediaWiki:Vector.css for vector. MediaWiki:Common.css will also work for all skins)

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:

How do I customize the link-URL of the site-logo in the top left corner of all pages that activates when the site-logo is clicked upon?
By default, clicking the site-logo takes you to the main site-page. If you want to change which internal site-page is the "main" site-page, edit MediaWiki:Mainpage.

To make the link of the site-logo link externally to any other arbitrary URL, you can add a hook to your LocalSettings.php to override the mainpage href which is used by the logo.

Here is an alternative way using jQuery code within MediaWiki:Common.js:

How do I change the icon in the browser's address line (favicon)?

 * Simply upload your favicon.ico to the root of your domain/subdomain, make sure file name is in lower case and its name is favicon.ico
 * Alternatively edit the setting in LocalSettings.php and add

See for more details.

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 Vector or the Monobook skin are determined by the MediaWiki:Sidebar page there on your wiki. For information on customising these, please see Manual:Interface/Sidebar.

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.

You can also add text to MediaWiki:Anonnotice to create a message that only displays for logged-out users. It is often a good idea to transclude the site notice on the anon notice to make sure that logged-out users still get the information on the site notice.

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?
Simply click on the "Move" tab, and move the page to the desired page title.

Usually you also want to change which page is the configured as "main page".

How do I hide the main page title?
MediaWiki does not have a built-in option to hide the main page title (see ), but you can use CSS to hide the title. Alternatively, you can use the extension.

Add the following to on your wiki:

If your main page uses a localized name or you have renamed the main page you need to change the  part. You can find a correct parameter by viewing HTML source of the main page and searching for the  tag.

For example, if your language is Lojban, the body tag looks like this:

Therefore you should put this line in your instead:

If you would like to hide the title of a "Main Page" in a specific namespace like "Help:Main_Page" add the following to on your wiki:

Note the difference:  in comparison to. The latter will not work.

If this doesn't work, you may be using a skin that doesn't support this, or you moved your main page without updating MediaWiki:Mainpage, or you have a really old MediaWiki version.

If the skin uses a different element for the title than a  element with class , you'll need to find the appropriate CSS selector to apply for that skin.

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. Er zijn meerder manieren om het te verberen.


 * Voor een enkele pagina
 * Plaats het magische woord  in de wikitekst van de pagina.


 * Voor alle pagina's
 * Installeer
 * or
 * Voeg de volgende regel toe aan MediaWiki:Common.css:


 * Per gebruiker
 * Users can add the same CSS rule to their common.css personal stylesheet.

Hoe kan ik de weergegeven taal veranderen?
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. Zie ook.


 * Een lijst met systeemberichten is beschikbaar op Special:Allmessages
 * To switch off the MediaWiki namespace, see the  configuration setting
 * To remove the Privacy policy or Disclaimers links at the bottom of each page, set the content of pages MediaWiki:Privacy or MediaWiki:Disclaimers respectively to a single hyphen.

Hoe kan ik de weergegeven taal veranderen?
To change the default interface language, alter the value of  in , for example

You may also need to bypass your browser's cache to see the changes.

The new default interface language will be applied to all users who haven't ever customised it.

If you want to provide users the possibility to create and choose pages and interface elements in languages other than the default one of the wiki, you need the extension, which can make your wiki multilingual.

If you want to change the language settings for all existing users, use the maintenance script. For instance, to have all users with English set use French instead, run:

How do I remove the "Talk for this IP" link at the top right (e.g. when is true)?

How can I suppress actions and special pages?
Suppressing actions and special pages can be useful when you want to create the illusion of a static website via a particular URL or VirtualHost, but also have an 'internal' view that is a true wiki. i.e. if you have an inward facing 'view' of your wiki that users can edit, and an outward facing 'view' that should appear like a static website (no history, no discussion, etc., etc.).

After hiding all the appropriate links (see above), if you are using the Apache web server, you can disable actions and special pages using the following rewrite rules:


 * 1) Lock down the site (disable MediaWiki commands)

RewriteEngine On


 * 1) RewriteLog /tmp/rewrite.log


 * 1) RewriteLogLevel 9


 * 1) See https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:Parameters_to_index.php#Actions

RewriteCond %{QUERY_STRING} (.*action=.*) RewriteRule .* http://www.my.domain.com?

RewriteCond %{REQUEST_URI} !^/index.php/Special:Search RewriteCond %{REQUEST_URI} ^(.*Special:.*) RewriteRule .* http://www.my.domain.com?

RewriteCond %{QUERY_STRING} ^(.*Special:.*) RewriteRule .* http://www.my.domain.com?
 * 1) Catch a trick...

Above, a request for, for example, will be simply rewritten to. Similarly any page in the Special namespace (with the exception of Special:Search) will be rewritten to. Remember, this is only a hack, and isn't intended as a solution for a secure CMS.

Note that you will need to adjust the above rules to match your specific URL naming schema.

Other issues to consider when trying to lock down a site like this is the API and POST requests for the wiki content (rather than GET).

How do I edit error messages?
Special:Allmessages contains a complete list of messages (error or otherwise), that can be edited.

How do I change the footer?

How do I add a reply link to default signature tildes ( ~ ) template?
You can customize signatures in MediaWiki:Signature / MediaWiki:Signature-anon.

For example, changing the entries to  will put a link to users' talk pages and   would give a more direct link.

Users can change their signature in their preferences.

How can I change what the 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, etc., 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 to edit the protected entries in the MediaWiki namespace.

If you want to change the title in your browser, you need to edit MediaWiki:Pagetitle. Go there and edit it just like you would any other page in your wiki.

In recent versions of MediaWiki, MediaWiki:Pagetitle is $1 - by default. If is producing the wrong text for you, you need to set  in your LocalSettings.php.

Don't forget to clear your browser cache after you change your settings.

Does MediaWiki automatically capitalize the first letter of $wgSitename?
Ja. Dit kan veranderd worden met de $CapitalLinks instelling.

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.


 * Administrators can delete an old revision of a page by deleting the page, and then selectively undeleting revisions to be kept
 * For newer MediaWikis (1.14+), you can enable the core RevisionDelete feature that allows privileged users to remove single revisions from page histories.
 * The  maintenance script can mass-delete all old revisions of pages and their associated text records.

How do I use a template as a signature?
When you look at your preferences, you see a check box for "raw signature." But the field will only take a certain number of characters. What if you want more?

You will need to create two pages, possibly in your userspace.


 * 1) Create the first page (FIRST PAGE)
 * 2) Go to your preferences, check "raw signature" and put  in the signature.
 * 3) Create a second page (SECOND PAGE) (possibly a sub-page of the first)
 * 4) Go back to the first page (FIRST PAGE) and do
 * 5) Go to the second page (SECOND PAGE) and place the code you wish to have for your signature.

If you don't have this structure, you will still be inserting all your signature code into the raw code wherever your signature is used, because the software will insert "SUBST" in your preferences. You may not mind this, in which case you only need one page. If you want the raw code to only display, which looks a lot cleaner, then you need to use the two-page structure.

How do I add the sandbox functionality to my installation of the wiki?
In wiki terms, a sandbox is simply a "play pen"; a page which users can mess about in. This is an ordinary page created in the normal manner, and can be located wherever you like. There is no special sandbox functionality built into MediaWiki.

Users often inquire about the Wikipedia sandboxes, which seem to be self-emptying. This is not quite correct; there are a number of volunteers who run bots to clean these up and return them to a certain state at regular time intervals.

How do I add a "Sandbox" link to personal tools (top right)?
You need to install the extension.

How do I make my wiki serve all languages?
To make your wiki multilingual and a tool for translation, allowing translation of pages and of the custom interface (like the sidebar), use the extension; there's extensive documentation.

Importing from MediaWiki XML dumps

 *  See: 

Importing from other types of wiki software
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 -p < ImportStage3.txt

Importing from other types of files
There are a variety of tools available to help convert content from HTML (and other formats) to MediaWiki markup.


 * Developer and SysAdmin tools
 * HTML::WikiConverter::MediaWiki - a Perl module for converting from HTML to MediaWiki markup.
 * Wikificator - a JavaScript MediaWiki extension that converts XHTML to MediaWiki markup.
 * The and  maintenance scripts can be used to import text and images into MediaWiki.


 * End-user tools
 * wikEd - a text editor for MediaWiki that can import HTML (including Microsoft Word-generated HTML.)

Templates imported from other wikis (such as Wikipedia) don't work for me
You probably need to install some extensions used on the source wiki, such as, , or sometimes. Also, make sure that you copied all site CSS and JavaScript required by the template.

I want to have multiple wikis, but only require registration once
You can share other tables as well, as long as they don't contain any data dependent on non-shared tables or data specific to one wiki. See Manual:Shared database for examples and more information. It has a few more features than a shared user table, but it's more difficult to configure and it's tailored toward a Wikimedia-style setup. However, it is easier than attempting to completely merge multiple user tables into one.
 * If you're starting from scratch or you're switching from one wiki to multiple, you can use and  to have all wikis share the user table of the "main" wiki.
 * If your wikis are already established and you want to switch to a single sign-on, you can use the extension.

How do I fix problems or add features to MediaWiki?
The basic steps to improving MediaWiki (that is, becoming a MediaWiki developer) are:


 * Install Git
 * Download the Git "clone" of the MediaWiki source code
 * Get a server, a database, and PHP running on your computer (this can be annoying, so please ask for help if something isn't working)
 * Get MediaWiki running on your computer off that Git checkout (can be annoying as well, so, ditto)
 * Fix the problem or add the feature you were thinking of
 * Edit the source code of the relevant file(s) to fix the problem
 * Follow Gerrit/Tutorial

The OutputPage class includes an addMeta method which can be used to add meta tags. The RequestContext can be used to get the relevant OutputPage object.

To add further Meta tags just add further lines as last lines of the function addMetaTags like:

…is the Help namespace empty?
The Help namespace currently ships in a blank state. It's up to you how much or how little help you give to your site visitors and whether this relates to other aspects of your site. Obviously you can easily link your visitors to help resources elsewhere.

We don't currently have a clean, internationalised set of help pages under a free license. However, if you want to copy in some help information onto your site, about how to use a wiki (a MediaWiki powered wiki) you are free to copy the from this wiki. This set of pages have been deliberately created for this purpose, with wiki-neutral information, and no license restrictions. See Project:PD help. More help is available at the Meta-Wiki MediaWiki Handbook.

…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  and, in some cases, a warning about potentially dangerous files.

To fix this, run the  script from the command line. This will set MIME information for each file in the database.

Recent versions of MediaWiki implement responsive images. Due to a bug, if the server locale is set to one that uses commas instead of dots for representing a decimal point, images may not render on some browsers/devices. This can be confirmed by inspecting a thumbnail of a medium or big image on a page with the browser tools, looking at the HTML code, and see if the  attribute contains commas instead of dots when representing the   value.

…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.

…can't I download MediaWiki {{#expr:{{MW stable branch number}}+.01}}?
MediaWiki 0000 is in a development state at present, and has not been packaged into a general release. The code can be downloaded from Git if desired. Or, if you want the latest development version packaged as an archive, get it at (GitHub).

…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, pulled from the current development branch. Coupled with the use of several extensions, this means that functionality between these wikis and your particular setup may differ.


 * To obtain the current development code, read Download from Git
 * To check what version a Wikimedia wiki is running, as well as what extensions are installed, visit the Special:Version page for that wiki
 * You may also be missing several that are installed on Wikipedia, see #Templates imported from other wikis (such as Wikipedia) don't work for me

…do I get a 403 Forbidden error after setting permissions on my Fedora system?
Fedora Core enables by default. Instructions for setting SELinux permissions for MediaWiki are available.

…do I get Installing some external dependencies (e.g. via composer) is required?
Many web hotels only handle zip archives, and we only provide gz compressed tar archives, thus the archives has to be recompressed before uploading. This should not be much of a hurdle, but it seems like some archive tools occasionally fails to include all files in large archives. When this happen the vendor folder is left out, leaving the user with the rather non-explanatory error message.

Use a command line tool when recompressing the tar archive into a zip archive.

…do I get logged out constantly?
This is probably related to cookies or session data. See Log in problems for information.

If this is happening constantly to all users, it probably means that caching is misconfigured. Setting  can be used to determine if caching is the cause of the problem. If that solves the problem, you should still investigate what is wrong with your caching configuration.

…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 this row from the User table?

Rob Church posted the following regarding this issue on the wikitech-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:



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 extension."

Another option is to give Admins the 'hideuser' right, and indefinitely block the user with the Hide username from edits and lists option selected.

is also useful.

…is the number of pages so low on Special:Statistics?
By default, is set to. This means the number of "Content pages" on the Special:Statistics page only counts pages which include at least one internal link. This can be changed by setting  to. Afterwards, run and/or. (On Wikimedia websites,  is run on the 1st and 15th of each month.) There might still be wrong behavior, see for example T212706.

Where do I get the spam blacklist from and how do I install it?
The spam blacklist extension can be found in Git, just like all other officially supported extensions. For installation and configuration instructions, consult the file and  over here.

How do I use $wgSpamRegex to block more than one string?
is a powerful filter for page content. Adding multiple items to the regex, however, can be awkward. Consider this snippet:

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.

Nine times out of ten this is because you didn't clear your cache. The simple test for this is to request a page that hasn't been requested before. Select the part of the URL in the address bar that contains the page title (e.g. Main_Page). Twiddle your fingers on the keyboard for a while, hit enter. Check if the problem is on that page too.

MediaWiki uses both a server-side cache and a client-side cache, so clearing your browser cache is often not enough. See the relevant entry above for more details.

Here are some other things to check:

Upload it into your web directory and invoke it with your browser. Check the document root and the path to php.ini. Did you create a duplicate entry in php.ini? Add new settings to the end of LocalSettings.php, not to the beginning. Ask your hosting provider.
 * Were you editing the right file? Try inserting some garbage into the file you edited, does it break anything?
 * A great debugging tool in this case is to create a file called phpinfo.php, containing only.
 * Were you editing the right part of the file?
 * If you created a .htaccess, are you sure AllowOverrides is on?
