The requested URL was not found on this server error - php

Question

I'm trying to create a website with Twig and Silex but I get a 404 Not Found error when I want access to /test page.
http://127.0.0.1/public_html/M1-CSI/web/ works.
http://127.0.0.1/public_html/M1-CSI/web/test doesn't works.
.htaccess
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
</IfModule>
Routing file
<?php
$routes = $app['controllers_factory'];
$routes->get('/', 'Sources\\Controllers\\ExempleController::exemple');
$routes->get('/test', 'Sources\\Controllers\\ExempleController::test');
return $routes;
Controller
<?php
namespace Sources\Controllers;
use \Silex\Application;
class ExempleController {
public function exemple(Application $app) {
return $app['twig']->render('exemple.html.twig', array('exempleValue' => 3));
}
public function test(Application $app) {
return $app['twig']->render('test.html.twig');
}
}
Thank's a lot.

Problem solved.
I added these code lines :

Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
in /etc/apache2/sites-available/000-default.conf
