After PHP update ISPConfig not accessible anymore

Hi.
Today i got a big PHP update (7.0, 7.2, 7.3, 7.4, 8.0) for my Debian 9 Server. After this update the ISPConfig 3 Control Panel is not accessible anymore (HTTP ERROR 500).
I also did a ISPConfig update from 3.2.1 to 3.2.2 but that didn't helpe to fix the problem and i also got some PHP Warnings.
/var/log/apache2/error.log

Code:

Update finished.

 

The config files "/etc/apache2/conf-available/php*-fpm.conf" had the correct entry.
I had to do this to fix my problem but i can't use php8.0 and i had mpm_event running before.

Code:

a2dismod php7.0
a2dismod php7.2
a2dismod php7.3
a2dismod php7.4
a2dismod php8.0
a2dismod mpm_event
systemctl reload apache2
a2enmod mpm_prefork
systemctl reload apache2
a2enmod php7.0
a2enmod php7.2
a2enmod php7.3
a2enmod php7.4
a2enmod reload apache2

Here is the Error i get when i use mpm_event or mpm_worker not sure why php8.0 won't work with mpm_prefork anymore.

Code:

Considering dependency mpm_prefork for php7.0:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:

 

Yes the command "ispconfig_update.sh --force" now works also without any warnings or errors.
Not sure what the heck they do with those PHP updates. Whiteout the help i would probably never have figure this out.

 

I would suggest this: https://www.howtoforge.com/communit...php-and-restore-if-changed.83288/#post-412147

 

This problem with the "/usr/bin/update-alternatives --set php /usr/bin/php7.X" i had a few weeks ago.
But now with this weeks big PHP update there is a new problem. Where i had to switch to mpm_prefork and disable PHP8.0 for the Apache server to start again.
Never had problems since Debian 7 but looks like now i get all the problems in one package.
