title: Always getting 404 error with Symfony
body: <p>I am a beginner into Symfony, and I'm having troubles to made it works. I'm running apache 2 on my machine (ubuntu). It seems that I can reach the configuration by the url:
  localhost/Symfony/web/config.php</p>
  
  <p>Also, I can reach the main page by this url:
  localhost/Symfony/web/app_dev.php
  (the first I see is a message telling: An error occurred while loading the web debug toolbar (404: Not Found). Do you want to open the profiler?). The only thing I can is to respond is cancel (If y try accept, I get a 404 not found).</p>
  
  <p>After that, nothing works. Even the . Always 404 not found. </p>
  
  <p>As I can found, it can be a problem with the cache or maybe with apache config. But whatever I try it doesn't solve the issue (other people ask similar here in stackoverflow, but nothing fix for me). </p>
  
  <p>Anybody knows? Thanks in advance.</p>
