How to modify the defaut new virtual server landing page?

Since recent update when I create a new virtual server, instead of the old cool 403 error page I got a default page.
An index.html file is pushed in public_html on create.

I found the template it seems came from in
/usr/share/webmin/virtual-server/default/index.html

Is there an admin for this ?
What is the best way to personnalize it ?
Because it may be modified again on nexts updates ?

Best,
Chris

You can put any index.html you want in /etc/skel/public_html (or whatever directory you have configured to be your skel for the given server template). This is how a default website has always been done in Virtualmin, now we just generate one if it doesn’t exist.
