Attempt to restore results in infinite redirect loop for unauthenticated users

[dudeval]

I tried upgrading from Civi 4.4 to 4.5, and it seemed to work as long as I was logged on as admin, but when I tried testing it as an anonymous user, it resulted in an infinite redirect error. I figured it was a problem with the upgrade so I tried to restore from a backup, but after the restore, it seems the same problem persists. The strange thing is this is that even if I completely disable CiviCRM and all of its associated modules, I still get a 'too many redirects' error as an unauthenticated user. Has anyone experienced this? Or have any idea where I should be looking to fix it? I'm at a complete loss here...

If the problem persists when CiviCRM is disabled, then the issue is solely a Drupal issue.
