One of my group members somehow has TWO entries for his name in the group’s Members list. I wrote him this:

“It looks like you’re in this group twice. I was going to try to delete one of you, but it looks like the only option is “Kick and Ban”. … So let me know when you see this, and I’ll attempt to delete one instance of you in this forum. Just saying in case […]”

He wrote back:

“I think you invited me to join. Then when I went to the page, the invitation wasn’t there, so I requested membership. Before you accepted my request, I realized that I could accept your original invitation by following the link from the e-mail. Then you accepted my request to join. Voila! Double membership! Now do I get 2 votes?”

I’ve got the same problem with duplicate group members. Since the group in question has 2 administrators I’m wondering if BOTH group admins received and accepted requests resulting in 2 instances of the same members in the group. There should be some test to see if a user is already a group member but that doesn’t seem to be the case. The link below is another example of the same issue. I’m running BP 1.2.3, WPMU 2.9.1 with subdomains.

If I don’t hear any possible causes/solutions, I’ll report this as a bug.

Glad you found this and thanks for updating TRAC!

@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…

Cheers,
Hans

To whom it may concern: I solved the issue by manipulating (not deleting) the doubled DB entry. In the wp_bp_groups_members table, I manually set both the group_id and user_id fields to high values that have no corresponding real equivalents (group, user). Think this now orphaned row won’t do any harm and as far as I can see, the searches like “groups of this user” or “users of this group” result in what I want now.
