Panels on the front page get invalid $user variable I have a Drupal 7 wite where the front page is a Panel. In one of its tiles I have a custom PHP code that prints out the value of `$user->name'. Now the problem is that it usually prints out a different user's name.

Cacheing and memcache is now switched off. Do you have any idea what might cause this problem..?
Ok, got is. Panels have its own caching that was switched on.
