Change default index.html when creating subdomanin

Hello,
I searched the file that creates the index.html when you make a subdomain or a domain in the CyberPanel, but I didn’t find it.
Can you help me with the actual location of that file?

I added a screenshot to see what file I’m talking about.

found it… /usr/local/CyberCP/index.html

have some way to define forever? Every update, need make reconfig of that file.

just open index.php in your new webbsite if you want that with installation you can do that is a bit hard one
