too long

Question

I am facing one issue. I could not get the home page while using CodeIgniter HMVC pattern and the below error is coming.

404 Page Not Found

The page you requested was not found.

I am providing my code below.

application/config/config.php:

$config['modules_locations'] = array(
    APPPATH . 'modules/' => '../modules/',
);

application/core/MY_Controller.php:

<?php

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

/* load the MX_Router class */
require APPPATH . "third_party/MX/Controller.php";

/**
 * Description of my_controller
 *
 * @author https://roytuts.com
 */
class MY_Controller extends MX_Controller {

    function __construct() {
        parent::__construct();
        if (version_compare(CI_VERSION, '2.1.0', '<')) {
            $this->load->library('security');
        }
    }

}

/* End of file MY_Controller.php */
/* Location: ./application/core/MY_Controller.php */

modules/site/controllers/site.php:

<?php

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

/**
 * Description of site
 *
 * @author https://www.roytuts.com
 */
class Site extends MY_Controller {

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

    function index() {
        $this->load->view('home');
    }

}

application/config/routes.php:

$route['default_controller'] = 'site';

Here I am using HMVC extension of CodeIgniter 3 but I could not found the simple page.
