PHP 8.0.1

Hello,
I am experiencing a problem with ISPConfig panel. That's my fault. I am here to ask to you how can I change the PHP version used to parse the panel's code.
*** The story ***
Today I did

Code:

apt update
apt upgrade

I noticed that PHP 8.0.1 was installed on the system. My websites are working but the panel died.
I tried to switch the system-wide PHP version by using

Code:

update-alternatives --config php

But nothing happened.
I also tried to add a custom handler on the /usr/local/ispconfig/interface/web/.htaccess

Code:

RewriteEngine On
Action php-cgi /usr/bin/php7.3
# THIS ONE #
AddHandler php-cgi .php
# OR #
AddHandler application/x-httpd-php .php

But the panel still uses PHP 8.0.1.

Can you help me to figure out how solve this problem?

Code:

Ok, solved thanks. I had to

Code:

service apache2 restart

 

I use script with monit to monitor such changes and I shared it in here: https://www.howtoforge.com/community/threads/monitor-os-default-php-and-restore-if-changed.83288/

 

wow great thanks so much for the awesome ISPConfig and for making it easy.
I ran this:

Code:

update-alternatives --config php-cgi

selected php-cgi7.4 option 7 for me
and then

Code:

service apache2 restart

, and back to php 7.4.x
Now ISPConfig admin is back up as expected.

 

I never run the newest version!
