Apache uploads (gives for download) php instead of executing it

Question

Im using Virtualmin on top of Webmin to configure my websites on a VPS.

Everything worked fine, but now I try to create a new domain, but when I put files in its public_html it gives the php-files to download instead of executing it. How to solve this

These is my apache config (can't find anything strange):

Answer 1

Try commenting out the line

php_admin_value engine Off

It's related to a larger issue that I'm still researching, but a recent update to Virtualmin added that line to some FCGI-related config files, breaking some things for some users.

Answer 2

As the accepted answer has said comment out

php_admin_value engine Off

We had this issue moving a site from one Virtualmin Install with PHP 5.X to a new server with PHP 7.1.

What had happened is that the default configuration for PHP7.1 had the following

<IfModule mod_userdir.c>
<Directory /home/*/public_html>
    php_admin_flag engine Off
</Directory>
</IfModule>

This stopped virtualmin from running PHP scripts in users directories by adding that flag to all the local .conf files.

The php7.conf file /etc/apache2/mods-available/php7.conf also had the following

SetHandler application/x-httpd-php

This was causing all child sites to run with the process www-data and not the virtualmin user. Causing write access errors. So comment that out also.
