I recently upgraded my forums. I don't if its that which caused my memberlist page to not work or if its something else. I might have disabled it manually by modifying the scripts or something but I want it back and I don't how to. Can someone help?
I would hazard a guess that you have a folder called members in the root of your XenForo installation so Apache thinks you're trying to access the members folder instead of index.php/members (which is then rewritten to just /members).
