Access denied for the user #1 I'm getting a 403 error everytime I try to log in with the user #1.

What can I do to get access again?

I have already tried to:


clear all cashes (via Drush)
set the time in both the server and Drupal's timezone, to be sure it isn't a cookie expiration problem
The problem began after I uncommented and defined a wrong $cookie_domain, in settings.php. (I needed this set up for FCKeditor/CKFinder.) Once I have corrected this, I've managed to log in again.
