MyBB Community Forums

I have many users who for some reason recieve a message that they are banned from my forum. They never had an account or anything. It is very weird....

How can i fix this issue?

Will pay 10-20$ to the person who can help me fix it.

What kind of message? Quote it and provide your board URL.

Also, paid requests should be done here: http://community.mybb.com/forum-190.html - this is a forum for free support.
