title: Symfony 2 debug toolbar not showing
body: <p>The Symfony debug toolbar doesn't show up.</p>
  <p>I am running the site on app_dev.php environment. The config_dev.yml file contains the following lines.</p>
  <pre class="lang-yaml prettyprint-override"><code>web_profiler:
   toolbar: true
   intercept_redirects: false
  </code></pre>
  <p>app_dev/php doesn't have any IP restriction. It runs AppKernel with dev environment. Also, AppKernel contains the following line.</p>
  <pre class="lang-php prettyprint-override"><code>$bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
  </code></pre>
  <p>The main problem could be the HTML markup, but it has both the opening and closing <code>&lt;body&gt;</code> tags. I even tried to remove all the HTML, and just leave it with few HTML tags, without luck.</p>
  <p>Is there anything else I could try?<br />
  Maybe some files could be missing. How can I check it?</p>
  <p>This is not a fresh Symfony installation.</p>
