title: Symfony profiler throws 404
body: <p>I've created new project in symfony and I get an error prompt on each site:</p>
  
  <blockquote>
    <p>An error occurred while loading the web debug toolbar (404: Not Found).<br>
    Do you want to open the profiler?</p>
  </blockquote>
  
  <p>When I open the profiler there is a message </p>
  
  <blockquote>
    <p>Token not found<br>
    Token "59942c" was not found in the database.</p>
  </blockquote>
  
  <p>Moreover, in the cache directory the profiler directory is empty! I checked permissions and they're proper. I tried <code>cache:clear</code> and removing cache manually, but that didn't help.</p>
