On a server with CloudLinux installed and CageFS enabled, changing a website’s PHP version in cPanel may produce the following error and prevent the PHP version from being updated:

Config file (Cannot read /etc/cl.selector/selector.conf: [Errno 2] No such file or directory: "/etc/cl.selector/selector.conf". Native used) not found

The original article describes connecting to the server over SSH and running:

yum groupinstall alt-php*
