I deleted cache/adminmenu.php and set cache/ to 777 but still get the same error. My browser is configured to send HTTP_REFERER.

edit: I turned on debug and when I tried to get back to the main menu it now tells me "This is your first time to enter the administration section. Press the button below to proceed."
I click below and it brings me back to the same page.
