Tried to install plesk 9 in a fresh 2008 Windows (64bits) and it only works for a couple of hours, then suddenly it stops working with the following message: HTTP Error 503. The service is unavailable Tried to restart with no avail the only way to resolve this is reinstaling plesk, and the after a couple of hours it starts again not working ? whats wrong ? also does Parallels suport work ? And why is plesk bloated with ads ?? And why are we paying a license to show ads to our customers ??
