You say you are using BP 1.1.3.
When you upgraded from the BP 1.0 series, what choice did you make when you upgraded the forums?
Did you choose to keep the existing installation?
Or did you choose to create a new installation?
Also how dependent are you on your external version of bbPress?
Besides the group forums, do your members post in other areas in your external bbPress?
After answering these questions, we’ll have a better idea on how to proceed.
