Hello, I have been using WPMU just to try on my brand new VPS server, It is very slow when I am using any plugins from WPMU hopefully I will see more improvement. What I need you to look at is "domain mapping" I have never had success .
I need to connect this domain for example: http://demo1.demo.com to http://demo1.com/ . From my demo on dashboard, Tools - Domain Mapping - I have entered "Map new domain name" the result of "Health Status" is "Invalid." So why invalid? When the domain name I wanted to redirect to is fully working also, it uses the same IP address or name server.
