Facebook logout problem php solved

After two days of searching, i have found a problem solved link and i wanted to share it with you all. Put this line in your logout script before redirect to Facebook logout.

$session = $this->facebook->getSession();

$logoutUrl = $this->facebook->getLogoutUrl(array('next' => base_url(), 'session_key' => $session['session_key']));

setcookie('fbs_'.$this->facebook->getAppId(), '', time()-100, '/', '.domain.com');

$this->session->sess_destroy();

redirect($logoutUrl);

I got it from this link http://forum.developers.facebook.net/viewtopic.php?id=71219.

Hope it help someone.
