Create New Website - Can't specify domain!

[snowweb]

When I click "Add new website", I'm presented with a form in which the form control for specifying the website domain is a dropdown box, which I obviously can't type my domain name in and it is not already in the list.

How can I add my domain to the list in the dropdown or type my domain please?

Thanks.

I've managed to solve this on my own now.

Goto System > Interface Config > Domains and remove the check mark from "Use the domain-module to add new domains", then click 'Save'.
