CI update from 1.7 to 2.0 getting Fatal error: Class 'CI_Controller' not found in CodeIgniter.php on line 210

[eluser]InsiteFX[/eluser]

Code:

public function __construct()
{
    // you need to add this when extending all CI core/libraries.
     parent::__construct();
}

Also Aken is correct you cannot use get_instance, because CI is not loaded yet.
