nginx serves some (but not all) php files as downloads
For running Wordpress behind Nginx, this works for me:
location / { # try_files $uri $uri/ =404; try_files $uri $uri/ /index.php?q=$uri&$args; } location /wp-content/updraft { deny all; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; }I also recommend reviewing the sample files from the Wordpress-Nginx project. In particular, you may also be interested the globals/restrictions.conf file, which hardens your installation somewhat. If you have several Wordpress sites on the same server, they can all share these "global" configuration files, making your life as a Wordpress admin easier.
