Hello, I've started a Wordpress MU installation and I want the domains to read "www.xxxx.com" but, the usual option for the domain preference seems to be missing from MU. Does anyone know how to add the www to the MU domains? Thanks in advance.
That's something that you should have set at the installation. Mu will work with the "www" although I can't see why you would want to. It makes it so much leaner without it. Here is an article that should help you hack it back: http://wpmututorials.com/hacks/forcing-mu-to-use-www/
