Strangely, my entire /wp-admin/ sub-directories have become inaccessible, including the CSS to the login screen. When I go to mydomain.com/login I get the login screen without any css. After trying to login I get a "cannot be found" page from my theme. Anything else I try, even when manually trying to view the CSS via browser path, I am getting the "not found" error. The files are definitely there (checked via FTP).
I've checked that my IP address is not locked out. That's all fine. The table is empty.
I'm puzzled and frustrated. How can I disable your plugin via the backend / FTP to get back into my WP dashboard. I am completely locked out.
