Hi i have a problem when i logout from vBulletin 3.5.4 using PHP5 SOAP version with joomla.

Warning: Invalid argument supplied for foreach() in /includes/connector/joomla.class.php on line 107

i have been looking in the file and it is the following that causes the problem:

PHP Code:

    function logout()
    {
                if(is_null($this->__res))
                {
                        return $this->__status;
                }
                $lifetime = time() - 1800;
                // cookies setzen
        foreach ( $this->__res->_cookies as $name => $value)
        {
            setcookie($name, $value[0], $lifetime, $value[1]);
        }
        // force logout, falls _cookies nicht exestiert
                setcookie( "usercookie[username]", " ", $lifetime, "/" );
                setcookie( "usercookie[password]", " ", $lifetime, "/" );
                setcookie( "usercookie", " ", $lifetime, "/" );
        
    } 


I have noted it doesnt happen with my non admin profile.
What could be the problem of this?
