I'm trying to setup Mediawiki behind Nginx with PHP-FPM. I found an old config that the Nginx wiki used to use? I get a 403 when accessing wiki.example.com, and a blank page when accessing index.php, test.php (a file I made with phpinfo() to test) and non-existent pages.

I've attached my configuration file and the output of /var/log/nginx/access.log

The environment is a fresh CentOS 7 box with the EPEL-release version of Nginx, SELinux is disabled. I have Mediawiki symlinked into the root of /var/www/wiki.example.com/public_html/mediawiki/
