Today I tried to disapprove a new registrant (spammer) and got a 406 error. Right now the forum is unreachable.

After some research it seems it may have to do with mod_security and I've asked to have it disabled. Has anyone had an issue with mod_security? Is there a specific rule, or rules that causes the problem?
