When I go to the admin, Magento request the user and password as it normally should but after I enter my credentials and send I am seeing this:

enter image description here

If I enter anything in there I go back to the normal login page, any ideas?


  • Deleted var/session and var/cache
  • Changed session backend to DB in local.xml
  • skin/adminhtml/default/default/css folder is untouched (I compared it to stack code)


The site has been suffering from a series of attacks because of this AMI and after the incidents, I decided to restore snapshot and install all security patches by myself and I ended up not being able to access admin portal by the described behavior.

This was solved by reverting security patch 7405 by trial and error reverting every security patch installed. I will still have to install it back taking the issues mentioned in this question into account.
