Someone installed this client's site and somehow screwed it up. The users and the profiles are missing from the dropdown menu for superusers. If you go straight to the users.php file, the edit button has FILENAME_USERS instead of users on it. A hint as to what to do to fix this would be great. It must be a database thing? I've made sure the correct admin files are uploaded to admin. There has been some work done in admin but not anything major that I can see.
