title: try_file is not using fastcgi
body: <p>I am running Wordpress through nginx and php-fpm. When a file that exists is requested, it works fine but when try_pass attempts to rewrite the URL to index.php, the browser just downloads the source of the PHP file. How can I get try_files to pass index.php to fastcgi?</p>
  
  <p>Here is my nginx config</p>
  
  <pre><code>server {
          listen 80;
          listen [::]:80;
  
          root /home/gausie/mywebsite.com/;
          index index.php;
  
          server_name mywebsite.com;
  
          location = /favicon.ico {
                  log_not_found off;
                  access_log off;
          }
  
          location = /robots.txt {
                  allow all;
                  log_not_found off;
                  access_log off;
          }
  
          location / {
                  try_files $uri $uri/ /index.php?$args;
          }
  
          location ~* \.php$ {
                  fastcgi_split_path_info ^(.+\.php)(/.+)$;
                  fastcgi_pass unix:/var/run/php5-fpm.sock;
                  fastcgi_index index.php;
                  include fastcgi_params;
          }
  
          location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
                  expires max;
                  log_not_found off;
          }
  
  }
  </code></pre>
  
  <p>I've basically borrowed this from the nginx wiki so I can't see why it doesn't work!</p>
