Virtualmin PHP old version prestashop not working

[dsxsoft]

Hey, I have a problem, I have ubuntu 20.04 with the virtualmin panel I have a prestashop store which after selecting php in the server configuration -> php version for the latest php 7.49 works but after changing to recommended by prestashop 7.3 the page does not work there is an error 500 mysql is not connected. After changing to the newest everything works, only presta does not fully load because php 7.3 is recommended. I installed with ssh sudo apt-get install apt-get install php7.3 php7.3-mysql php7.3-cgi php7.3-cl, I change version to 7.3 and there is error 500 what to do?

You would simply need to look at Logs and Reports/Apache Error Log, follow an error upon calling the script and fix it accordingly. It may be permissions error or missing PHP extensions or something else. Nevertheless, that is something pretty easy to fix, when you see an actual error.
