Codeigniter to cPanel

Hello guys. I badly need your help. I am currently an intern in an NGO. My job is to create a CMS for the organization. I followed a tutorial about creating a CMS. Actually it worked on my localhost. Now I will be moving it to the live server. I already uploaded all necessary files to cPanel. when I tried accessing it via (http://ngoWebsite.com) it showed a 404 error.

Here is my setting of my index.php before uploading it to cPanel:

APPLICATION ENVIRONMENT:

switch (dirname(__FILE__)) {

case 'C:\xampp\htdocs\ngoWebsite':

define('ENVIRONMENT', 'development');
break;
default:
define('ENVIRONMENT', 'production');
break;

ERROR REPORTING:
if (defined('ENVIRONMENT')){
switch (ENVIRONMENT)
{
case 'development':
error_reporting(E_ALL | E_STRICT);
break;
case 'testing':
case 'production':
error_reporting(0);
break;
default:
exit('The application environment is not set correctly.');

}

Here is the structure of my cPanel:
home/ngoWebsite
     >public_html
        >all my files here including index.php

Thanks in advance.
