I have raised the question in open ticket and someone has helped me fixing things
Just trying to get back from him about what has been done and Can I fix it by myself if it occurs again in the future. Basically I am sure I put it as an AddOn Domain (not a parked domain either) and still not sure what happen... Oh Well...
For right now, it is working, I wouldn't want to try fixing the working things. I will try your suggestion if something happen in the future.
Webuzo is kinda unique. It should have been automated and GUI based, but for some reasons these things happen, though it has been much better than last year
