Having exactly the same problem here having upgraded to WP 2.9.1 and BP1.2 last night. Blog associations not showing in the “My Blogs” drop down from the Buddypress Admin Bar, or through their profile pages. All blogs and user associations seem to be correct in the back end, though. Help!
Yes – having the exact same problem. My site users are not able to see the Blogs there are associated with under the “My Blogs” drop down in the main Buddypress Admin bar in the front end. Again, this is after an upgrade to WP 2.9.1 and BP1.2.
