Check out the latest update of Archi version 3.5.0!
Does it matter if you install WHMCS on the main site or on a subdomain when it comes to getting it working with the theme? I’m new to WHMCS, but I’ve read that some people prefer to keep there billing in a subdomain separate to the main site.
Hi, maybe there are some issues when install WHMCS on main site (some our customers)
So i think you should install WHMCS on separate domain.
