We have a VPS Server Running Centos 7.3 with WHM & Cpanel installed. Our goal is to have our company Email and web hosting services hosted on a single server with Odoo 10. I installed Odoo 10  with instructions from: https://www.rosehosting.com/blog/install-odoo-10-on-centos-7-with-apache-as-a-reverse-proxy/ and was working just fine. After changing our domain name we are experiencing "500 internal server Error" .  I need help to fix this or uninstall the odoo and re-sinstall it.
