Re: group membership: double membership bug?
@3sixty: I experienced exactly the same misbehaviour in my blog = invitation sent, membership requested by the blog member, confirmed twice somehow and… boing, 2 memberships of the same member in a single group.
Is it still there in your blog or could you fix it?
I wonder if it was sufficient to simply delete the doubled/second group-member-relation entry from the MySQL wp_bp_groups_members table? Or does this have any negative side effects?
A more gentle alternative could be to set the group_id field of this entry to a non-existing group 999 or so. Shouldn’t do any harm unless the 999th group is created and an uninvited member pops out of nowhere…
