Answer 1

Reading the comments of that tutorial, many people are having the same problem with that code. Did you change parent::CI_Router() on line 10 to parent::__construct()?

But why not just set the $route['404_override'] variable?

Answer 2

Just set a proper route in your config/routes.php:

$route['404_override'] = 'your_controller/show_404';

And the corresponding controller would look like that:

class Your_controller extends CI_Controller {

    function __construct() {
        parent::__construct();
    }

    function show_404() {
        $this->output->set_header("HTTP/1.1 404 Not Found");
        $this->load->view ('common/errors/404'); //wherever your view is
    }
}

That should do the trick for you.
