figured it out. i had installed the “friend connect” plugin, and in the settings of that plugin i had checked “Allow only Google Friend Connect users to login WordPress” so i just unchecked that and now it works again.
thanks for your help Ipstenu!
whenever i try logging back in as admin, it does not let me click on anything in my dashboard. i will get the note “cheatin, uh?” or “You do not have sufficient permissions to access this page.”
