Myself and a friend of mine decided to start a pet site. Got it up and running, modified the theme and sidebar. Everything was fine. But somewhere along the way, things went a little wonky.
My friend can't log into the admin and she is a "root admin". First user group, just like me. Using the right password and everything. First I thought it was related to the issue where people weren't able to log into the main site, but seems that isn't it. She can log into the regular site, just not the admin.
And apparently upon logging out, she can't log back in. Mine works fine. I can access everything. (First person to register.) I had her re-register and she was able to get in the first time, but when I changed her access to Root Admin and she logged out to try logging back in, didn't let her back in.
Well... Nevermind. I figured it out. Thanks anyway.
