If your domain is hosted with Namecheap, in order to point the site to the WPX server, you will need to change the Nameservers.
Login into your Namecheap account and select the Domain List menu on your left.
Locate the desired domain name and press the Manage button.
Once you have entered the Manage menu locate the NAMESERVERS field.
From the dropdown menu select the Custom DNS option.
The Nameservers can be found in the original Welcome email that you received when the account was activated. They can also be found in your WPX Hosting Dashboard (1) → Service Details (2) at the bottom of the menu, under Server Details:
In the two fields, fill in the details for Nameserver 1 and Nameserver 2 and press Save.
Keep in mind that the technical time for full DNS propagation is 48 hours. In some rare cases, it can take up to 72 hours, that’s just the nature of the way that the Internet was built.
