Here is my problem. Sometimes the plugin needs an update, but does not show anywhere. This is very agitating, to me at least. When I update plugins there is always one that does not show in the list to update. I read in a thread somewhere that it is a deleted plugin that still has stuff in the database that has not been removed. So my question is this. Is there a way to find out what is causing it, and to delete it? Perhaps a plugin that will do it? I have searched for such with no results.
