Pretty urls not working (404) – Router does nothing

Hello,

I want to implement pretty urls on my page, e.g. like that: localhost/example/news/show/6
I get only 404 Not Found when navigating my browser to that url.

Code in my RouterFactory:

public static function createRouter()
{
        $router = new RouteList;
        $router[] = new Route('<presenter>/<action>[/<id>]', 'Homepage:default');
        return $router;
}

Part of the template with link:

<p> {$new->text|truncate:50:" ..."} <a n:if="strlen($new->text) > 50" n:href="News:show $new->id">>Show the whole article</a></p>

Presenter of the page link is pointing to:

<?php
namespace App\Presenters;

use Nette,
    Nette\Application\UI\Form;


class NewsPresenter extends BasePresenter
{
    /** @var Nette\Database\Context */
    private $database;

    public function __construct(Nette\Database\Context $database)
    {
        $this->database = $database;
    }

    public function renderShow($id)
    {
        $new = $this->database->table('news')->get($id);
        if (!$post) {
            $this->error('Post not found');
        }
        $this->template->new = $new;
    }
}

I am using apache2, linux mint 17.2 64bit,
access rights are set to +rwx to entire folder where my project resides,
mod_rewrite is enabled.

When I change Router to SimpleRouter in RouterFactory, everything works, except URL parameters are used for routing, what is not acceptable.

Does somebody know what is going on?
Thank you
