I setup Virtualmin on my new VPS based on CentOS 7 and, following the documentation on this site, successfully switched from Apache to Nginx. I see that PHP version is 5.4.16 which is outdated. I would like to upgrade to PHP 5.6 or 7. However, when I go to Server Configuration > PHP Versions I see this message only:
“Website options cannot be edited, as no Apache virtual host for hotthem.es port 80 was found!”
I followed instructions and installed PHP 5.6 for CentOS 7, and restarted my VPS, but Virtualmin still use PHP 5.4.
How to switch to higher PHP version?
