I tried installing:
apt install php-mbstring

But it didn’t work either.

So you installed module but mb_strtolower() still doesn’t exist? That seems like a problem with your configuration. Still, the plugin should gracefully handle this function not existing by at least giving a error notice that says it is not available.

The underlying library, highlight.php, is using this function.

@allejo Is it possible for highlight.php to have a fallback mode for when mbstring is not installed?

I have a pull request open to add a graceful fallback for this method. Multibyte case conversion is only needed when you’re highlighting a language that has Unicode keywords (e.g. 1c); so you can safely live without it for most usages.
