Thread:Project:Support desk/Login error (2)

Hello, I have a problem on my website: bravelywiki.org. I cannot not enter my user account there, and the strange problem is, it happens when a user obtains administrator rights. I have no idea what causes this strange problem, or it might be a bug, or it depends on the version of the MediaWiki. It is such a bother, because it clearly acts that way towards contributors that has administrator rights or bureacrat rights. And that caused me to prevent to log into my user account.

Hopefully you guys can help me out what the problem is. I thank you for your time.
