Whm/cpanel, crazy thing happened


Jun 7, 2004
Hello all,
i have customer with subdomain , he purchased domain name and asked me to set it for him.
I went to whm and i modified his subdomain and i put his new domain.
Now i still have his subdomain working and his domain name point to the server:
this the situation:
*cpanel: i can see his account as a subdomain of my domain
*whm: when i list accounts i canot see both subdomain or domain name but when i went to bandweitdht usage i can see his domain name with exact bandweidth statistics.
Crazy thing, no?

Well, now what to do to see his domain name in listed accounts?
How to be able to run his domain name and not his subdomain?

Thank you very much ( it is urgent!)
