I updated my blog ( http://forgottenliberty.com ) last night to the newest WP version and everything seemed to work, but this morning, my blog’s homepage is not displaying and when I try to log in to wp-admin it tells me “invalid username”. I can still log in to my Cpanel and access my file manager. All my WP files are still there. I’m not a WP or web site expert so I have no idea what going on. Has my site been hacked or did something go wrong with the upgrade? Any help would be greatly appreciated.
