Debian 6. Two server mirror setup Apache Perfect server I am trying to setup new servers... I've setup my templates, created a client.. when I try to add a new mail domain, or site domain I get the following error ERROR Domain is empty. Domain is empty. Invalid domain name.
Just a guess: You activated the domain limit function but did not add the domains for the clients first in the client module. So either you deactivate the domain limits under System > interface config so that you acn add the domain in the web settings directly or you add the doma first in the client module and then select it from the list in the web settings when you create the website.
