Unfortunately, turning "Off" to "On" here doesn't make a difference, 
which is not too surprising given that I had already commented out this 
section of php7.2.conf (which didn't help). Again, Apache can run PHP 
scripts in this user directory, including DokuWiki.

Nevertheless, I guess that the problem is due to something in Ubuntu's 
Apache configuration ...
