PHP Warning in cron.log

Hello,
I just upgraded to ISPConfig 3.2.11p1 (on a Debian Bookworm up to date).
To make sure everything is ok I took a look at the logs, notably /var/log/ispconfig/cron.log and I found PHP warnings that there should not be:

Code:

My default PHP version is:

Code:

php -v
PHP 8.2.15 (cli) (built: Jan 20 2024 14:14:18) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.15, Copyright (c) Zend Technologies

    with Xdebug v3.3.1, Copyright (c) 2002-2023, by Derick Rethans

I know these are just warnings, but I would like to know if you know where they could come from?
My version of PHP? Something else ?

Thanks in advance for your ideas
Laurent.

 

Thanks Till, perfect as usual.
There is no Hurry of course !

 

FYI: I have similar error, but with a warning + an additional in monitor_system_update

Those kinds of PHP warnings may be caused by running the program under wrong PHP version.
