Hi!
How better to set access for clients to the Vision only through WHMCS?
Let me remind you - this should work for different domains.
WHMCS for different domains running on different servers, and the Vision host shared by some virtual domains.
That is - need to perform a redirect, depending on which of the virtual domain in the request.
Any ideas, please
The option is to change WHMCS default support module with vision support module.
It does not matter if your whmcs for addon domains are on different servers.
