I previously set "View user's profile page details" to members only. But then changed it to allow viewing by guests for all future registrations. I also changed the permissions to "allow" guests to view a lot of existing member profiles by manually editing. Now when a member whose profile was previously not visible to guests but now visible after editing the individual permissions - makes a profile post, it still does not show for guests in the sidebar widget. Do I have to run any DB query?
