stimw its a known bug, will be fixed in the upcoming release (i don't know precisely when)

This issue should be fixed by updating your forum dependencies. It was an issue in another project that Flarum uses to perform formatting on posts.

@JoshyPHP released an update to s9e/TextFormatter which switched out the broken CSS for a different one a few days ago: https://github.com/s9e/TextFormatter/releases/tag/2.9.4

Sure, thanks to the contributors for their work.

davwheat Thank you. The problem has been solved.
