unable to open virt links inside of virt

I am in the virt template list and i tried clicking hte little preview window icon next to each content style and i get this:

Warning! Webmin has detected that the program https://etc-md.com:10000/virtual-server/thumb_style.cgi?style=modernclassic was linked to from an unknown URL, which appears to be outside the Webmin server. This may be an attempt to trick your server into executing a dangerous command. Make sure your browser is configured to send referrer information so that it can be verified by Webmin.

Alternately, you can configure Webmin to allow links from unknown referers by : •Login as root, and edit the /etc/webmin/config file. •Find the line referers_none=1 and change it to referers_none=0. •Save the file.

I should not have to edit this due to the fact i am inside an established, ssl connection.
