Hi hillel,
thank you very much!
You helpt me to solve the problem!
For your and maybe other interest:
I am used to have my php.ini in /etc/php/8.3/apache2/php.ini
So i edit this, but this was not the php.ini the webserver used…
The right one was shown in the phpinfo and was in /etc/php/8.3/fpm/php.ini
After i edited this, everything works!
Thank you again
