HHVM Detected Clash Configuration - nginx

Question

I'm using Ubuntu 14.04 and trying to install HHVM alongside Nginx. Both installed fine except when running the command below I ran into a clashing issue. Can anyone point me in the right direction?
Note: I placed the code from hhvm.conf to my nginx/sites-enabled/default config as suggested elsewhere.
Command:
sudo /usr/share/hhvm/install_fastcgi.sh
Error:

WARNING: Couldn't find Apache2 configuration paths, not configuring

WARNING: Detected clashing configuration. Look at /etc/nginx/hhvm.conf for information how to connect to the hhvm fastcgi instance.

Answer 1

The problem was due to a bad Nginx install and configuration. Removing both Nginx and HHVM (including config files) solved this.
