HMVC codeigniter works on local server but not on web server

Question

this is killing me

what do i have? CI version: 2.1.4 Modular Extensions - HMVC by wiredesignz a basic codeigniter(hmvc) project that works fine with the setting it has in local server(mamp) with php 5.5.3

my problem after i move the project to public web server i changed the following things. ——application/config/config.php

$config['base_url'] = 'http://example.com/';

——application/config/database.php

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'newdbusername';
$db['default']['password'] = 'newdbpassword';
$db['default']['database'] = 'newdbname';

ErrorDocument 404 /index.php

since my index page will be the index function of ‘home’ module, i have not touched routes.php file in application/config folder. below is the settings for routes.php

$route['default_controller'] = "home";
$route['404_override'] = ''; 

THE PROBLEM whenever try to access http://example.com/ i get the message below

404 Page Not Found The page you requested was not found.

i get same message if i try example.com/home but example.com/welcome still gives welcome to codeigniter page

WHAT IS GOING ON!!!??? why cant i access any of my page from modules?? what have i missed?? is anyone else getting this problem??

ps: my cpanel has php 5.3.27 if that helps

Update:: below is my default controller's index function

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

class Home extends MX_Controller
{

function __construct() {
parent::__construct();
}
function index()
{
    $this->load->library('recaptcha');
    $data['recaptcha_html'] = $this->recaptcha->recaptcha_get_html();
    $data['view_file'] = "checkmember"; 
    $this->load->module('templates');
    $this->templates->checkinfo();
}

============

UPDATE 2

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

class Welcome extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL

     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in 
     * config/routes.php, it's displayed at http://example.com/

     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $this->load->view('welcome_message');
    }
}

/* Location: ./application/controllers/welcome.php */

Answer 1

I figured the problem was not with HMVC but was with codeigniter version 3.0. When it comes to unix(which was the operating system running on my server), it is case sensitive. So when I tried to access the controller it could'nt find the file because of case sensitivity and a 404 popped out everytime.

My folder structure before was something like :

-application
-->modules
--->users
---->controllers
----->users.php

And the link on which I was getting 404 was www.example.com/users/login

where "users" in the link is controller's name within the "controllers" folder under "modules" folder in my case named as users.php and "login" is the function inside the controller.

All I had to do was to change the case of the first letter of my module and controller name. Now my directory looks like

-application
-->modules
--->Users
---->controllers
----->Users.php

note : capitalized "U" in Users module and Users controller.

And the the url I used to access the users controller was : www.example.com/Users/login

And I was good to go.
