Hello, I have a similar problem. On Centos 7.7, versions of PHP 5.4.16 and 7.1.33 are already installed. I am trying to add 7.4. All packages are installed, php is accessible from the command line (/bin/php74), but the latest version is not found at “Re-Check configuration”. update-alternatives was launched, replacing CGI mode with fcgid given nothing. What am I missing?
