Topic on Project:Support desk

Today a bug was reported to me where when editing a page, it told them (another Sysop) that they did not have permission to edit it. I checked, and they're still a sysop. What's more is, this is effecting every single user on the wiki, including myself, and we all still have our permissions. The edit button is gone, but when viewing the source of a page, or trying to create a new one, we get "The action you have requested is limited to users in one of the groups: Users, Administrators, Bureaucrats, editor." despite belonging to those groups.

I have no idea why this is happening. I tried disabling cloudflare, but it doesn't seem to have any effect. The site is not in read only mode either, this happened out of the blue this morning.

Cloudflare should have nothing to do with this. Are you sure no settings in LocalSettings.php were changed before this? The only logical explanation is that a setting changed.

$wgReadOnly is off/commented out, so it's not that. I have not touched anything regarding permissions in several months. The only things I've changed recently is adding the extensions Number Format, Category Test, Labeled Section Transclusion, and DynamicPageList. It all worked fine when I installed them.

Is there anything in specific I should look for in my LocalSettings.php?

As a test, you should try temporarily disabling all extensions to make sure that it is not an extensions problem. An older version of Extension:Lockdown was one extension which caused similar rights issues.
