can you please answer these questions so i can narrow down what the issue might be??
has this issue always been there when you first installed bbPress?
did you import any forums and this issues has started?
did you install any plugins that modify s the capabilities of users?
is your default WordPress role for registration a subscriber in settings>general?
have you had a large amount of spam lately?
have you had any security issues lately?
Right now i cant tell what what causing the issue?? It is either some capability plugin settings that are messed up , or that you have been hacked??
