Websites don't work

Hey,

All of my websites don’t work with virtualmin.

Thats what i do:

  1. Install Virtualmin on an clean CentOS 7.2 minimal via install.sh
  2. create an Virtual Server
  3. copy website to /home/xxxxxxx/public_html
  4. next i go to the url

and here is the Problem it downloads the index.php file.
here you can test it self: http://nova-arts.net/

[Edit]
Found the Problem but why is this standard for every Server?
I set under Virtualmin > Services > Configure Website > PHP > PHP Admin Configuration Values: engine Off / to On

so how can i set this automatic for every new virtual server?

I get this problem only with PHP 7.X versions, older than 5.5.9 works perfectly.

Is your version of PHP 7.X ?

Note: your resolution is correct, the problem will be solved changing
Virtualmin > Services > Configure Website > PHP > PHP Admin Configuration Values: engine Off / to On
