I can honestly say that it was working one minute and not working the next - I can NOT log onto my wordpress admin panel because of this error...Please help.

traced the issue to a 302 redirect that was generated at login so just went to a non-broke site and copied the url and changed the domain to get past that redirect. To do it use this url with your settings
You'll be able to login here. In my case the NextGen plugin was in need of a critical update. I updated it and problem went away

This one worked very well for me. I was able to log into my previously inaccessible backend.
In my case, it was the misbehaving staff-directory plugin that was causing the login error.
Thanks a lot to JerryOdom.
