404 Page Not Found on my live server

I have the following config.php:

PHP Code:

$config['base_url'] = 'http://'.$_SERVER['HTTP_HOST'].'/myfolder';   
$config['index_page'] = 'index.php';
$config['uri_protocol'] = 'AUTO'; 


This works fine locally , but when I upload the project to the server ,
when I call the following URL :

http://example.com/myfolder/  

or

http://example.com/myfolder/index.php

It comes an error message: "404 Page Not Found"

Why?

You can try to change the file name of controller to ucfirst
