NGINX on Debian ships with new configuration files
I just updated the nginx package which delivered new configuration files and caused the php-fpm worker to fail. There was no error message in none of those files
Restarting nginx did not help. When I noticed HTML files got served correctly but PHP files didn’t, I noticed a difference between my old
/etc/nginx/fastcgi_params and the new one.
nginx new default
To fix php-fpm, you can manually add the line
fastcgi_param SCRIPT_FILENAME $request_filename;
I uploaded my full paremeter list to pastebin.
