Unable to load your default controller with HMVC and real host

[eluser]greedyman[/eluser]
I get an error when try to upload code to my host http://z191.com/estore/:
Unable to load your default controller. Please make sure the controller specified in your Routes.php file is valid.

I tried to fix this problem follow some way I found in forum but this error is still (delete CI controller folder, model folder; change default file name controller ... ). Here is my folder structure:

routes.php

Code:

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

What should I do? This is the first time I've uploaded my code to real host, I run it on localhost and it works fine.

Your module default controller should be the same name as the module.

Code:

// Rename home.php (controller to front and it should work using the route below.
$route['default_controller'] = "front";

It means that I have to change home.php to front.php? I changed but nothing happen.
