I created new VPS with Ubuntu 14.04 and fresh Virtualmin install. All went great. Then I restored virtual server from Virtualmin from Ubuntu 12.04 to the latest Ubuntu server. Now I receive error 403 Forbidden.
I found a tip http://www.virtualmin.com/node/33473 to go to system settings > server templates > apache website change here : allow from all to : Require all granted.
I did, on two places.
The same problem.
