Why do website not show after uploaded to host?

Your should check out your configurations (are your using 'index.php' in your url) I think you should write chome  instead  of cHome, some server are case sensitive.

Is your website working on local server ?

Here is my configurations in file config.php :

PHP Code:

$config['base_url']    = 'http://nhacchonloc.zz.mu';
$config['index_page'] = '';
$config['uri_protocol']    = 'AUTO';
... 


I'm using free host of Hostinger,domain is 'http://nhacchonloc.zz.mu'. I changed 'cHome' to 'chome' as the same that you said, or changed

PHP Code:

$config['index_page'] = ''; 


to 

PHP Code:

$config['index_page'] = 'index.php'; 


but the result still was not changed anything. 
When I entered the address URL is 'nhacchonloc.zz.mu/index.php/cHome', home page was showed, but when I redirected to the other page, any the page,  it showed "error_404?"
