title: Symfony - Nginx Configuration error : FastCGI sent in stderr "Primary script unknown"
body: <p>This is the first time I use nginx with Symfony, and I used the configuration that is on the Symfony document. I have the basic configuration of the latest version of nginx.</p>
  
  <p>However, on my url: 127.0.0.1:83/app_dev.php/fr/admin/organisations</p>
  
  <p>I get the error in my nginx project_error.log file : </p>
