Hey i found a problem with xoops..

Ok here is the problem:

If i use other domain from the real domain of the site e.g if the domain is myname.com and i buy another one called myname2.com then every user who joins the site with the name site myname2.com he cant login as a member. I found this problem in another site This is fixed with the new version or not? did anyone tell us again about this problem?

Please help because i want to change my site name and i cant use other domain than the real thanks venix
