Default DocumentRoot directory redirects to a VirtualHost in Virtualmin

view story

http://serverfault.com – When I try to access DocumentRoot it redirects to one of my VirtualHosts, I can't see contents in /var/www/html. It's under Virtualmin 3.94 and I think someone else my problem here, but I can't find the options he tried to fix. How can I fix this please? (HowTos)
