When I activate Headway Community Builder (http://headwaythemes.com/extend/addon/community-builder/) and WPMU's Membership plugin at the same time it causes BuddyPress activity updates to double-post. When either one is active with the other inactive activity updates work just fine.
I really want to use both of them in tandem. Any ideas what could fix this?
I've also posted this situation on the Headway forums.
