Maybe it is because I made an Update yesterday: pkg_jfilters-1.20.0_PRO.zip

Hi
The error is strange in the 1st place, because even if those mbstring functions do not exist in your PHP version, Joomla loads the Symfonly/Polyfill to incroporate them.
So, that means that both your PHP version does not support/include mbstring functions (or not all of them) and your Joomla installation does not load the Symfonly/Polyfill library.
The action that will solve your issue right away, is to upgrade your PHP version to php 8.4.0 or higher.
We are also considering releasing an update with a fix, since this was reported by others as well.

Thank you for your quick answer, but my PHP version is high: PHP 8.2.29

Great!
I am closing the ticket as resolved.
If you find value in the extension and my support, I would really appreciate it if you leave a small review in the JED.
