When I updated from 3.198 to 3.202, only AHP was registered, all other plugins were not, and none of the others worked. When I closed AHP and restarted, 3.198 came up with all plugins registered and functional. Gary t reported the same type of problem back on March 10, so I tried the suggestions from that post, and attempted to update to another version (3.201). Same results.
So, 3.198 seems to be working ok but I can't update without losing the registration on the other plugins. Is there a specific reason this happens, or is it caused by "unknown file corruption"?
