sess_destroy()

[eluser]aggrav8d[/eluser]
I had a menu in a header file that was only supposed to appear when the user was logged in. When the user logged out, the menu was still visible. Turns out Session::userdata still existed, which meant that things like Adam Griffith's Authentication library failed to correctly assert logged_in()===FALSE.

TL;DR: Add this at the end of /system/application/libraries/Session.php(~410)

Code:

// Kill the cookie
        setcookie(
                    $this->sess_cookie_name,
                    addslashes(serialize(array())),
                    ($this->now - 31500000),
                    $this->cookie_path,
                    $this->cookie_domain,
                    0
                );
    
    unset($this->userdata);
    }

Cheers!
