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'; 

—-public_html/.htaccess

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
     *  - or -  
     *      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/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $this->load->view('welcome_message');
    }
}

/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */

Finally the problem was solved. this was my folder structure in modules folder.

—modules/

—————/home

————————/Controllers——->home.php

————————/Models——->mdl_home.php

————————/Views——->viewfile.php

all i had to do was change the capitalization on “Controllers”, “Models” and “Views” folders and i was back in business.

now the folder structure is like this and its working perfectly

—modules/

—————/home

————————/controllers——->home.php

————————/models——->mdl_home.php

————————/views——->viewfile.php
