BuddyPress.org

any registered if logged in, can’t see activity streams

@rajeev-jain very strange. As mentioned above, backup database. Deactivate all plugins except BuddyPress and bbPress and change to Twenty Twelve theme. Clear cache. Check if you can view Activity Streams now. If ues, then activate the Magazine theme and check Activity Stream. If all is go, activate plugins batch by batch and double-check Activity Streams to help you identify what is causing the visibility issue when logged in.
