Forum Registration problem since upgrading - banned forever issues- HELP!!!!
 

This the 5th person who has tried to register at our forum since the upgrade and in doing so or if coming back if they haven't been logged in for a few months are receiving messages that they are banned forever. ( they email us upset ). I checked users: it shows we have no banned members ( yet they are being told they are banned>?). I checked settings.

HELP!! What is going on here?
