  1. Open the file with your browser,

  2. A new password for the admin user is generated and displayed on the browser.

  3. Log in to the admin panel with the user admin and the new password generated.


The script recovery.php is going to try to delete himself but if this doesn’t happen we recommend delete the file recovery.php by hand.
