Nginx not serving files from changed document root - php

Question

I seem to be having an issue with my Nginx (version 1.11.9) installation. I have set up a LEMP stack on my Ubuntu 16.04 LTS server, and also have mail services running on it as well. I'm using the following agents :- Postfix and Dovecot. Now the reason for setting up LEMP is to facilitate webmail using Roundcube. I have set up symbolic links within sites-enabled, deleted link to default and added site config file called roundcube. The problem I am having is the default_server document root is not loading any pages from that location, it only seems to be loading pages from the Nginx default location /usr/share/nginx/html
I have specified root to be /usr/share/nginx/roundcube but no pages load from that location. I been going over this a 3 weeks now and I'm just getting frustrated as I cant see the issue. I will list the Nginx config files I have amended.
Any help would be very much appreciated.
P.S I am using Cloudflare DNS
Thanks Rob
