The default Mediawiki installed has been customized to make it a bit harder for spammers to overwhelm wikis with illegitimate content and comments. This is done by modifying the LocalSettings.php file (a file that is included in every install in which it is possible to provide configurations details).
By default, Mediawiki allows anonymous users to create pages and edit pages in the wiki. The modifications change this in the following ways:
-
Anonymous users cannot edit existing pages
-
Anonymous users cannot create pages
-
Registered users must click the confirmation link in the registration email in order to edit or create pages
This approach should drastically reduce unsolicited content and comments on Mediawiki installations. One further step that administrator might take is to turn registration off after a predetermined amount of time. Users must create accounts by this date; after that, the settings are changed so that registrations are no longer open.
To add this setting, you must edit LocalSettings.php in your Mediawiki install:
- Login to cPanel and browse to your File Manager.
- In the File Manager, browse to the folder within public_html that contains your Mediawiki install. If you installed the wiki at the root of your domain, you won’t need to go any further than public_html. If you installed the wiki in a subdomain or subdirectory, you’ll need to find the directory that is associated with that space.
- Locate LocalSettings.php. Once selecting the file, click download in the top menu bar to download the file as a backup before proceeding. Then click Edit in the top menu bar to edit the file.
- Confirm that you want to edit the file.
- Browse to the bottom of the document, and locate the custom settings that were added during the Mediawiki install and the following line:
$wgGroupPermissions['*']['createaccount'] = false;
