I could of course see the tables prefaced "wf" and deduced what those were. I am able to check for database integrity and table corruption myself via PHPMyAdmin; I also ran a phpinfo.php and everything is just fine. No, disabling and removing the plugin did not fix the problem. (Incidentally, I notice that removing the plugin--on several sites, not just this one--leaves the wf tables in the database and a folder on the server.) I have dedicated hosting, and again, I am able to see from shell access that server space is MORE than plentiful.
I hear what you're saying about it not being your plugin but I tried it on another site, different server, same result. Fortunately I use ManageWP for my 100+ sites and was able to restore in no time flat.
So thanks for trying to help. Certainly WordFence is a highly touted and respected plugin so my experience is not going to make any waves, and my sites are restored and using other security plugins so all is well.
Appreciate your ideas and trying to help! Have a great day!
