[SOLVED] how to build a forum in the domain of panel.

[freed1985]

The domain of my panel is cp.7x24idc.info.
Tho domain of hostname is server.7x24idc.info.

Now I want to build a forum with 7x24idc.info on this server.
But when I make the total dns to the ip address of this server.
It`s can only visit the panel.
The forum is install on a vhost of ispCP gofree.us
When I add the domain 7x24idc.info to the folder of the form in users gofree.us for domain alias.
It can`t visit the forum,It visit a default page for 7x24idc.info.
And the cp.7x24idc.info is linked to the default page too.Only can visit the panel with domain server.7x24idc.info.
How can I make the domain to the forum?
