Change http ports

[kwalkerk]

I'm already running a web service on port 80 on my PI.  After installing the Pi
Gateway, the startup script for that service gives the message that port 80 is already in use.  Can I change the default ports for the PiGateway?  If so where?

Thanks

I finally found it.

The nginx ports are defined in /etc/nginx/sites-enabled/default.

Made the change there an now everything works again.
