deploy laravel 5 ovh

I'm been trying with every tutorial to deploy laravel 5.1 app on OVH via Filezilla FTP. I'm always getting Internal server error or blank page.

I unzipped my project into root/ ( same level as www) then I copied public content into www.

/www

public content

/project ( has no public folder)

Done 777 chmod in storage folder.

htaccess in www folder

<IfModule mod_rewrite.c>

RewriteEngine On
RewriteCond %{REQUEST_URI} !^www
RewriteRule ^(.*)$ www/$1 [L]

index.php in www folder

        <?php

require __DIR__.'/../bootstrap/autoload.php';


$app = require_once __DIR__.'/../bootstrap/app.php';


$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);
