title: Symfony 2: "No route found for "GET /" - error on fresh installation
body: <p>I am trying to begin my education of symfony 2 and started with it's tutorial. One of first things I tried was to install symfony 2 and configure it.</p>
  
  <p>When I try to access <a href="http://127.0.0.1:8000/" rel="nofollow noreferrer">http://127.0.0.1:8000/</a>, I am getting an incomplete site with the following error:</p>
  
  <blockquote>
    <p>ERROR - Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No route found for "GET /"" at /home/spectator/webprojects/cls/app/cache/dev/classes.php line 2059 </p>
  </blockquote>
  
  <p>Things I have tried so far: </p>
  
  <ul>
  <li>clearing cache (<code>php app/console cache:clear --env=prod --no-debug</code>) </li>
  <li>recursively changing permissions to folder cls (symfony 2 folder) to
  <code>775</code> and even <code>777</code> (for diagnostics purposes) </li>
  <li>adding "/" route to routing.yml and routing_dev.yml</li>
  <li>reinstalling and </li>
  <li>re-chmod symfony 2.</li>
  </ul>
