I set up in a VM the latest Ubuntu Server 16.04 LTS for testing. Virtualmin installs Apache 2.4, MySQL 5.7, PHP 7.0. After setting it up and checking if is ready, PHP is not running with the webserver. Accessing a php file will get a download file. I tried many things but it seems Virtualmin is not creating any webserver logs in /var/log/virtualmin for checking what is wrong. Checking /var/log/apache there are no errors in those files.
When I give "apache2ctl graceful" command I am getting this error message:
[Sun Jun 12 23:41:38.567178 2016] [so:warn] [pid 3268] AH01574: module dav_module is already loaded, skipping AH00526: Syntax error on line 2 of /etc/apache2/sites-enabled/mydomain.ro.conf: SuexecUserGroup configured, but suEXEC is disabled: Invalid owner or file mode for /usr/lib/apache2/suexec Action 'graceful' failed. The Apache error log may have more information.
It seems something is wrong with suEXEC configuration. Any thoughts?
