CI on host, does not work

I have Xampp installed and locally my CRUD code Igniter works.

On the host, on the subdomain is giving 404 page not found. I uploaded the entire folder to a subdomain. The subdomain, created a folder that I named as ten. Below it the structure is identical to the local structure.

I've done:

• I changed the database configuration.php
• I changed the config configuration.php changing this item: $config['base_url'] = '/dez/';

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase dez/
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php/$1 [L,QSA]
</IfModule>

• I have already changed all the names of the Controller and model (putting the first letter in capital).
• I have already exchanged '$config['base_url'] = '/dez/'; for '$config['base_url'] = '/';
• and '$config['base_url'] = 'dez/'; by '$config['base_url'] = '/dez';
• inside .htacess I have already exchanged RewriteBase dez/ for RewriteBase

No routes.php ----> $route['default_controller'] = 'Dashboard';

Then in the dashboard :

<?php
  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    class Dashboard extends MY_Controller{
    function __construct()
    {
        parent::__construct();      
    }
    function index($indice=null)
    { ......

Within MY_Controller:

<?php 

class MY_Controller extends CI_Controller {

    public function __construct()
       {
            parent::__construct();

            $logado = $this->session->userdata("logado");

            if ($logado != 1) 

                redirect('/Login');             
       }
}

Then in the browser I type the subdomain name 'sie' and it appears https://sie.dezenvolvesolucoes.com.br/dez/Login and the IC message 404 Page Not Found

I took a test and exchanged Dashboard extends MY_Controller for CI_Controller. Then, the home page is "assembled", but without formatting the layout (css, js..). I check the source code of the page (without layout formatting) and see the links to the files .css, js ..

src="<?php echo base_url();?>assets/js/jquery.min.js">

And when I click on them, page not found . I go to CPanel and look for the files .css and js, all exist.

The current .htacess, is an example that I searched here in this link: https://gist.github.com/keithmorris/3023560

Nothing....
