I solved this by recreating each group using the info in the group forums listing, and by choosing not to create a forum for the group. After creating the new group, I went to Groups in the admin panel, selected the new group for editing, checked the ‘I want a forum for this group’ box, and chose my already existing forum group and associated it with the ‘new’ group. Glad I didn’t have a lot of groups(!) Also necessary, is to re-invite your members to re-join the groups. It seems all this could have been avoided by having more users than just myself as admins for the groups. Live and learn. I hope this helps someone, and if this isn’t in the documentation, I sincerely hope you will add it, along with a warning when someone is about to delete a user who is the creator and only admin of a group. Would be nice if you could be prompted to reassign the groups to another user, as is offered with posts.
