Debian 10 latest patches ISPConfig 3.2.2 PHP /.4 installed php -v PHP 7.4.15 (cli) (built: Feb 11 2021 21:22:21) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies with Zend OPcache v7.4.15, Copyright (c), by Zend Technologies under system alternate PHP Version PHP7.3 and PHP7.4 On my other system Debian 10 testing I had nothing to do but once the entries under system where there and I could select php version. Found server tutorials for multiple php version on the web, did not help need hint thanks Rainer P.S. Starting the installaler of TYPO3 11 it say PHP must bei 7.4 or above, while php -v tells me it is 7.4.15
So you have added PHP 7.4 as additional PHP version under System -> Additional PHP versions? Is the entry enabled? Did you assign it to a client? (You should not do this if you want to use it for anyone). By the way, the PHP version on the CLI should be 7.3, change it back with Code: update-alternatives --config php update-alternatives --config php-cgi
See here: https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/ And as Thom mentioned, you missed setting the correct default version.
