Thread:Project:Support desk/administrator listed twice in "Groups you can change" within "User rights management"/reply

Hi!

I think this might be caused by some kind of oddity in MediaWiki and by your configuration:

MediaWiki comes with an administrator user group predefined. However, this group internally is not called "administrator", but "sysop". I guess that in LocalSettings.php you have made some configuration in $wgGroupPermissions for a group called "administrator". This then creates a second entry with the same name.

The fix is to no longer use $wgGroupPermissions['administrator'], but to use $wgGroupPermissions['sysop'] in LocalSettings.php instead. Should you have a user account associated to the wrong "administrator" group, then you should add this account to the "sysop" group instead.
