Creating new virtual server in apache, pointing to a sub-directory of a multisite manager, but only giving default apache2 page

Hi all,

After creating a new virtual server using the Webmin apache control panel and pointing the server to a custom subdirectory of a multisite cms (expresssionengine in this case), I can only see the default apache2 webpage.

Here's the sites-available entry, dummy domain name

DocumentRoot "/home/cms1/public_html/sites/www.sitename.com/" ServerName sitename.com allow from all Options None Require all granted

Is this a permissions problem causing apache2 to automatically redirect? Would I be better creating a full virtualmin server and using filesystem links instead? Am I missing something really simple? Any help appreciated, Eoin
