CodeIgniter 2.0 with Modular Extensions (HMVC) not showing anything in Linux - codeigniter

Question

*edited to be more clearly
I'm deploying CI 2.0.3 with Modular Extensions (HMVC) in two environments, one is Windows -for development- and the other is Linux -for production-. Both environment has identically folders and files structure. Currently I am having a problem.
After integrating the Modular Extensions to CI by following the manual. The first thing I did was moving the default Welcome MVC that comes with CI to Modular Extensions HMVC. Both environment successfully moved and can be viewed on the browser.
But when I create other modules, it worked on Windows environment but not on Linux. On Windows when I call the module the browser shows the page as expected. But on Linux it shows just white blank page. Not even an 404 err page, which means it is not a broken link.
Can anyone tells me what is wrong in the CI?

Welcome controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index()
{
$this->load->view('welcome_message');
}
}
Csv_game_credit controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Csv_game_credit extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('Csv_game_credit_db');
$this->load->dbutil();
$this->load->helper('file');
}
public function index()
{
$this->load->view('welcome_message');
}
}
Is this has something to do with the Linux's folder permission? I will try to change the folder permission to 777 and update you guys
Thanks before

Answer 1

You need to extend MX_Controller not CI_Controller

Answer 2

If you are using the HMVC extension from wiredesignz you need to verify that you put the MX folder in the application/third_party folder and the MY_Loader.php and MY_Router.php in the application/core folder.
When this has been verified, create the folder modules in the application folder ('application/modules`).
Now, what is a little tricky about this solution is that when you wan't to create a module, the default controller has to be named the same as the module - the default controller name specified in the config doesn't apply here.
This means that if you create a module called `mymodule', you should create a folder/file structure like this:
application/modules/mymodule
- /controllers
- - mymodule.php
- /views
- - whatever.php
In the controller, located at application/modules/mymodule/controllers/mymodule.php you just create a controller as you would normally do:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Mymodule extends CI_Controller {
public function index()
{
$this->load->view('whatever');
}
}
