Setting up custom domains for users will give your users the ability to add their own custom domains to their account to create pages on the new domain.

To enable this feature for users, navigate to the Admin Panel -> Website Settings -> Audits tab and ensure that Custom Domains system is enabled.

Additionally, allow users to have this feature based on their plans, configurable from the Admin panel -> Plans section.

A user will need to connect his custom domain to your own before submitting it. Admin approval is required after setup to accept the custom domain.

I am on a shared webhost

If your website is hosted on a shared webhost with panels like cPanel, go to the Addon Domain page inside your cPanel and add all the domains that your users will add to their accounts. Make sure that the Root Directory of the new domain is set to the same directory as the already existing Product Installation.

I am on a VPS

In this case, you will need to make sure that all the extra domains from your users are added and configured on your server. Ensure that the Root Directory of the new domain is set to the same directory as the already existing Product Installation.

Configuration for Apache Servers domains is usually found in the /etc/apache2/sites-enabled/ folder for each of your existing domains on your server.

A good and simple solution that works in most cases would be to edit the 000-default.conf file and point the DocumentRoot and Directory to the already existing Product Installation. This way, all the domains that will be added will automatically be linked to the original installation.

Configuration of this feature is not offered in support as this setup is based on your host provider/server.
