Subdomains (sub-servers) are put outside of public_html by default.
Need to have default subdomain directory be a folder inside the root domain.
i.e. domain is thedomain.dom
Directory for thedomain.dom is /home/thedomain/public_html/
Subdomain of subd.thedomain.dom >> needs to be in default directory (not change every time) of /home/thedomain/public_html/subd/
