HELP! I did as suggested in Hardening WordPress and changed my database prefix to something other than wp_. I used the recommended official wp plugin "change db prefix", as I don't know enough yet to mess around with my databases manually. BUT once I activated the plugin, I got logged out of my wp-admin and cannot get back in again. And of course the catch-22 is, that I can't change the database back using the plugin unless I'm logged in to wp admin!!
What do I do please?
Is it possible that having Bulletproof Security activated somehow requires or calls to the databases by their old name?
