I have on our server several PHP versions. ISPConfig is taking for itself always the newest version (8) instead of 7.4. How can I set which version of PHP ISPconfig is taking for itself?
ISPConfig is not choosing the latest PHP version for itself, it uses the default version of the OS and if you set the wrong default version, then the wrong PHP version will get used.
