Problem logging out of Facebook site and wiping out sessions

I cannot get the facebook connect app I am building to register a user (sorry, no url as it is still in dev). Every time the user clicks on the link with the "logout" class, the following JS runs that seem to work and even show the mod is FB, stating that the user is logged out.

$(document).ready(function(){
    $('.logout').click(function(){
        //Kill facebook Session
        FB.Connect.logout(function() {
            window.location = $('.logout').attr("href");
        });
    });
});

      

        
        
        
      

    

Upon reaching the callback above, JS sends the user to a logout page where PHP again forcibly deletes the user session and ensures that the FB session is deleted. The user is then sent back to the page they were on when they clicked the "Logout" link.

//Remove our site session
Auth::logout();



/* FAIL
//Send user to FB logout page and then back here
$logout_url = $this->fb->get_logout_url( site_url( $return_to ? base64_url_decode($return_to) : '' ) );

// Clear any stored state
$this->fb->clear_cookie_state();

exit(header("Location: ". $logout_url));
*/



//FAIL
//$this->fb->logout( site_url( $return_to ? base64_url_decode($return_to) : '' ) );


//FAIL
//Remove user (is this needed..?)
//$this->fb->set_user(NULL, NULL);


//Remove the FB session cookies (in case the JS didn't)
$this->fb->clear_cookie_state();


// Redirect to privious page
redirect( ( $return_to ? base64_url_decode($return_to) : '') );

      

        
        
        
      

    

However, this whole process results in the user returning to where they were and still signed in. A second click on the link seems to do the trick and delete the session. I was tracking firebug (w / firecookie) and PHP logout pages were deleting FB session cookies, but still the next page loaded still uses them ?!

If anyone knows how completely DESTROY ALL FACEBOOKS ah ... sessions, then please speak up.

: EDIT: I even tried to manually delete all cookies on the logout page and still failed

if( $_COOKIE ) {

    foreach( $_COOKIE as $name => $value ) {

        //Get the current cookie config
        $params = session_get_cookie_params();

        // Delete the cookie from globals
        unset($_COOKIE[$name]);

        //Delete the cookie on the user_agent
        setcookie($name, '', time()-43200, $params['path'], '', $params['secure']);
    }
}
