This is running version 8.1.25 on a MacOS 14 system.

I have another system running Ubuntu 22.04 LTS and PHP PHP 8.1.2-1ubuntu2.14 where this is not happening.

What steps must I take in order to avoid these warnings?

Answer 1

Some third party libraries aren't compatible with the new version of PHP your going to have to wait for them to fix it or downgrade PHP.

Its not the first time 2121
