I'm a forum admin on a 3.0.6 forum. Over the last few days, we've had a major issue where large numbers users, moderators and our other admin have been banned from the site for no reason, and with no input from anyone. It appears now that anyone who stayed logged in is generally OK, but on logging out, users become automatically banned.
It appears to occur across all browsers, and there is no pattern to how it happens - users may get in on some systems, but not on others.
There is nothing on the Admin Control Panel to suggest there is a problem, and I don't have database admin access to the back end, so can't do anything other than whats available on the ACP.
I can't get in touch with the site admin / owner.
Any suggestions??? Really would appreciate some advice!!
