Can't open Kayako after moving to CentOS7 Nginx

Hi all,

We've been having speed issues on our current setup (CentOS 6.7, Apache 2.2.15, PHP 5.5.32, MySQL v5.1.73) and I was having issues installing Xcache (I believe due to the version of PHP or more the repository it was from) so I was building a new virtual server to save downtime.

Rather than going with the same setup I had before I decided to go with the following:
CentOS 7.2.1511 (Core)
nginx 1.6.3
PHP 5.4.16 - Zend Engine v2.4.0 with XCache v3.1.1
MariaDB 5.5.41-1

I've tested my PHP...
