I tried removing mythweb, php, apache, then rebooting.  Then reinstalled 
apache2, php, and mythweb.  Got the same errors when running mythweb, 
but slightly different results when checking the versions:

don at johnny:~$ sudo apt list --installed | grep -i php

WARNING: apt does not have a stable CLI interface. Use with caution in 
scripts.

don at johnny:~$

don at johnny:~$ sudo a2query -m | grep -i php
php8.2 (enabled by site administrator)
php8.1 (enabled by maintainer script)
don at johnny:~$

On closer inspection of /var/log/apache2/error.log, there's an error 
about the version check (Undefined constant "FATAL" in 
/var/www/html/php_version_check.php).  That leads back to the earlier 
suggestion, from the other thread, to adjust apache2 (adapted to the 
currently installed versions), by:

sudo a2dismod php8.1
sudo a2enmod php8.2
sudo systemctl restart apache2

Now Mythweb works fine.
