Основи


Які відмінності між MediaWiki, Wikimedia, Wikipedia та вікі?
Це загальне питання; будь ласка перегляньте для детальної відповіді.



Я хочу використовувати екземпляр MediaWiki для (порожньо). Чи дозволено мені?
MediaWiki це безкоштовне програмне забезпечення: це означає, що ви можете використовувати його з будь-якою метою без юридичних перешкод. Крім того, ці ліцензійні умови поширюються виключно на саме програмне забезпечення. Це означає, що, хоча багато вікі ліцензують свій вміст за дозвільною ліцензією, ви не зобов’язані ліцензувати вміст, надісланий у вашу вікі, якимось особливим чином. Звичайно, як проєкт, заснований для підтримки таких сайтів, як Вікіпедія, ми рекомендуємо вам ліцензувати тексти, які ви пишете, за безкоштовною ліцензією, але, коротше кажучи, від вас цього не вимагається.

Якщо ви бажаєте змінити або внести зміни до самого програмного забезпечення, загалом, вам дозволено, але є деякі обмеження, і вам слід ознайомитися з повним текстом GNU GPL версії 2 для отримання детальнішої інформації. Оскільки MediaWiki надається безкоштовно, немає жодних гарантій у межах, дозволених чинним законодавством.

How do I create a wiki?
Creating a wiki implies installing MediaWiki on a server and having access to manage it. There are different options, depending on your level of expertise:


 * To create a wiki on your own server, follow the Installation guide.
 * Some hosts offer one-click installs, or allow creating a wiki on-request. See Hosting services for different options.

This site (MediaWiki.org) or the Wikimedia Foundation does not allow individuals to create wikis.



Встановлення і конфігурація


Де завантажити MediaWiki?
Натисніть тут, щоб завантажити останню стабільну версію MediaWiki. Файли надаються в архіві .tar.gz. MediaWiki також можна отримати безпосередньо з нашого репозиторію.



Як встановити MediaWiki?
Встановлення MediaWiki займає від 10 до 30 хвилин і включає завантаження/копіювання файлів та запуск скрипту інсталятора для налаштування програмного забезпечення. Див. , де ви також знайдете мінімальні системні вимоги.



Як встановити MediaWiki за допомогою пакета?
Багато дистрибутивів Linux надають MediaWiki у запакованому форматі для цього дистрибутива. Команда розробників MediaWiki спрямовує вас до вашого дистрибутива Linux, щоб отримати допомогу з їх встановленням, налаштуванням або використанням. Окремі спільноти та компанії, які обслуговують такі пакети, повинні надати інструкції з встановлення.

Майте на увазі, що сторонні дистрибутиви можуть мати старіші версії, тому звертайте пильну увагу на інформацію про сумісність для інструкцій та розширень.


 * Див. також: 



Чи можу я встановити більше однієї вікі на сервер за допомогою MediaWiki?
На сервері можна встановити більше однієї вікі за умови:


 * Ви встановлюєте декілька екземплярів MediaWiki (наприклад, за допомогою пакета програмного забезпечення, такого як Bitnami MediaWiki Stack); в різних каталогах — по одному для кожної вікі

Або


 * Ви використовуєте різні бази даних для кожної вікі

Або


 * Ви використовуєте інший префікс бази даних для кожної вікі (для Postgres ви можете досягти подібного ефекту, використовуючи різні схеми та користувачів)

Щоб отримати інформацію про останні два варіанти, дивіться ' і ' відповідно.

Для отримання додаткової інформації про створення сім’ї вікі (вікіферми) дивіться.



Як встановити наявну вікі, як-от Вікіпедію чи Вікісловник?
Основним (але не обов’язково найпростішим) методом є імпорт. Дивіться нижче вікі-імпорт.

(Методи, які не належать до MediaWiki, такі як Xowa та Kiwix, можна знайти за адресою w:Wikipedia:Database download).



Чи вимагає MediaWiki доступ до безпечної оболонки?
Доступ до оболонки (SSH) не потрібен для встановлення MediaWiki, але настійно рекомендується. Без доступу до безпечної оболонки вам може бути навіть важко отримати резервну копію вашої вікі або оновити до нової версії. Деякі завдання технічного обслуговування взагалі неможливі без доступу до оболонки. Багато основних розширень найкраще працюють із доступом до оболонки.



Як встановити розширення?
Див. для отримання інформації про встановлення та написання розширень. Перегляньте, щоб знайти наявні розширення.



Як додати додаткові простори назв?
Див. Створення спеціального простору назв.



Як увімкнути завантаження?
Завантаження файлів є часто використовуваною функцією MediaWiki, але вимкнено за замовчуванням у всіх поточних версіях випуску. Щоб увімкнути їх, спочатку зробіть доступ до каталогу завантаження (за замовчуванням ) доступним для запису веб-сервером (  або дозвольте користувачу Apache записувати до нього, тощо), потім встановіть  на   у LocalSettings.php. Якщо під час спроби завантаження ви отримуєте помилку «не вдалося завантажити mkdir», це, ймовірно, означає, що є проблема з дозволами.


 * Див. також: 



Як дозволити завантаження додаткових форматів?
MediaWiki вимагає, щоб дозволені формати завантаження файлів були вказані за допомогою директиви конфігурації . Зазвичай ця директива знаходиться в LocalSettings.php в корені вашій інсталяції MediaWiki.

Наприклад, щоб розширити завантаження до файлів PDF, додайте таке до LocalSettings.php:

Щоб розширити завантаження до кількох типів файлів, використовуйте наступний синтаксис

Як очистити кешовану сторінку?
Щоб очистити кешовану сторінку, наприклад під час внесення змін до панелі навігації, додайте  в кінець динамічної URL-адреси сторінки.

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

How do I change default user preferences?
The MediaWiki default user preferences are in  Don't edit that file, just use it for reference.

Say if you want to hide minor edits in recent changes by default. DefaultSettings.php says:

To change the preference, put this in your LocalSettings.php:

To change the default namespaces to be searched, in any version of MediaWiki, set in LocalSettings.php to an array mapping namespace indexes to boolean values. For example, to search the main namespace and the category namespace, use:

In some cases, after you change a default user preference, you may also want to change the user preferences of all existing user accounts.

If so, use the script in the   directory. Use the --dry option for the first run, assess the impact and go from there. ( --dry does not write the database.)

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

Also, always backup your database before making these kinds of changes (you do not need to if you are just using --dry ).

Is it possible to move my wiki to a different machine?
Yes. It should be. In essence, you will be backing up your old installation and then "restoring" it onto the new machine. Finally, you will have to make additional modifications to update the wiki configuration so that everything points to the new location.

How do I move my wiki to a different server?
Follow the instructions at.

How do I change the logo?
The logo that appears in the top left of each page is determined by the configuration line in the  file.

There are two ways to change the logo:


 * 1) Upload a picture to your wiki using the normal file uploading interface. This allows the logo 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:
 * 1) Upload an image to your server by other means (such as FTP).
 * Add the $wgLogo line to LocalSettings.php, for example:
 * (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.

How do I edit the wiki's CSS?
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:

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:

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.

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".

MediaWiki 1.38+
The displayed title of the main page can be changed using the MediaWiki messages and  (for logged-out and logged-in users respectively). The main page title can be hidden by setting both messages to empty (or only either of them if the title should still be displayed to logged-out or logged-in users).

MediaWiki 1.37 and below
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. There are multiple ways to hide it.


 * For one page
 * Place the magic word  in the page's wikitext.


 * For all pages
 * Install
 * or
 * Add the following rule to MediaWiki:Common.css:


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

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.


 * For a list of system messages, see 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.

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

You may also add ?uselang=qqx or &uselang=qqx to a URL which will display the name of each messages in the interface.

How do I change the interface language?
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 article/edit etc tabs?
For a little more control see: User:Subfader/Hide_page_tabs

Edit MediaWiki:Common.css on your wiki, and add this:

See the page source for the various #ca-* ids used in the content tabs.

How do I add/remove tabs throughout my wiki?
See or write your own extension (See: ):

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 :

How do I remove the "Talk for this IP" link at the top right (e.g. when is true)?
One option is to hide the link using the following CSS in the wiki page MediaWiki:Common.css in your wiki:

Another option is, inside your LocalSettings.php file, to use the PersonalUrls hook to remove the link to the talk page of anonymous users:

How do I remove the "Create an Account or Login" link at the top right of the screen?
To remove the login / create account links from the personal_urls you can use this code in your to hook in and remove them:

How can I suppress actions and special pages?
There are two different ways:

Using .htaccess file
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:

Above, a request for, for example, will be simply rewritten to. Similarly any page in the Special namespace (except for Special:Search) will be rewritten to.

Alternatively, you may also serve a "403 Forbidden" for all such requests using:. 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).

Using LocalSettings.php
To disable a specific special page (such as Special:SpecialPages), you may use:

where  is the canonical (English) name of the special page to disable, and   is the message to be shown to users when they try to access the special page.

To disable an action (such as edit), you may use:

See to disable an API module.

This is only the basic usages. Usually you may want to disable special pages, actions or API modules conditionally.

How do I change the footer?

 *  See:, 

How can I edit / remove the Powered by MediaWiki image (and possible other images) from the footer?
You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css:

If you want to remove it completely, you can use to remove it using this in your :

Note that this will also remove other powered-by icons, e.g. also the one coming from BlueSpice.

If you wish to change the icon images, urls, alt text, or add new icons please see ' documentation.

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?
Yes. This can be changed using the configuration setting.

How do I change the background color?
To change the background color of the MediaWiki interface outside of the page content and tabs, add the following CSS to the MediaWiki page :

This will change the background color outside of the tabs, search, and page content to red. See for more information.

How do I load external fonts?
This example refers to Google Fonts, a repository of free open-source fonts that you can use with MediaWiki. Go to https://fonts.google.com/, find fonts that you like, and select them by clicking the "plus" (+) icon. Select one or more fonts to be added. Click the tab for the pop-up notification, and then select "@IMPORT". Copy and paste the resulting CSS into. The examples below use Noto Sans and Noto Serif. They are default fonts for Android operating system and have good support for Unicode text.

How do I edit a 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.


 * 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.

 * 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.

See also: Extension:SandboxLink which will add a link to user's personal sandbox (i.e. a subpage of personal user page) to personal tools menu.

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

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 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

…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.

MediaWiki 1.21 and newer implements 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 File is corrupt or has an invalid extension 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 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 hosting providers 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 a hurdle, but it seems like some archive tools occasionally fail 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 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 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.

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?
