I have noticed that a lot of users cant be found searching by the Username, email or whatever. The only way they can be found is to list them by their letter with the "Show User" tool. But if I choose "All Users" they are not shown.

Most of the users that are invisible have been registered within 9 months but not all!? Some users have been registered 4 weeks ago and still works.

Users that are invisible do work fine at the moment but when I try to upgrade they don't work anymore but they still exist in the databse.

Please help!!
