My website had many problems resulting from BuddyPress and BB during and after I uninstalled them. Then I screwed up procedurally changing my WordPress folder from /blog/ to root. Then it was also virtually destroyed by hackers, such that it was taking most of my day trying to clean up the messes and thus getting nothing productive done.
Installed Wordfence and cleanup became more efficient and now at last it's running fine again, and I'm able once again to proceed with real work. There are a few improvements I'll suggest, but not here. It works properly outta the box.
