Well, i'm new to virtualmin, but I already think this is awesome !
I created several Virtual Server, all at the same level. They work fine, but this time I created a virtual server with a domain name that I don't yet own. My point is that I wanted to work on the website, and when I'll have the domain name, I'll just have to change th IP.
So I created a virtual server as I would normally do, let's call it "fra.com".
I tried to create an alias from another domain to /home/fra/public_html directory. But I got a 403 forbidden.
In my directives of other domain :
Alias /fra "/home/framirex/public_html"
I tried to change permissions with chown chgrp (to www-data etc...) nothing worked.
