custom 404 page

How do you have your controller setup? Do you have your controller named "error" and then function called "error404"? As 200 is a success response....

I have mine setup as a main controller (main.php) with all the default pages (Including error pages)

So controller main.php

PHP Code:

defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller {
    public function __construct() {
        parent::__construct();
    }

    public function error_404() {
        $data['page_name'] = '404 Not Found';

        $this->load->view('static/header', $data);
        $this->load->view('static/404');
        $this->load->view('static/footer');
    }
} 


I have more stuff for if user is logged in etc. but this is the basics of it.
