I have not been able to log-in to my blog admin. panel for about 3 weeks now. We've tried everything possible posted online...
-Clearing cache, cookies, browsing history, etc.
-Renaming plugins folder and creating new directory
-Renaming WP-admin folder and creating new directory (when disabled, instead of redirect after logging in, we got a blank page)
-Disabling the blog's .htaccess
-Made sure cookies were enabled
-My IT dept. tried more fixes as well
-The latest copy my web hosting co. had of the blog was 2 days prior to lock-out, paid $79 to have them revert to that copy, still nothing
I'm at a loss here and not sure what to do next... please help!
