The problem is that the text is hard-wired in the post to be black, but the background is not set to anything. So when blackend makes the background black you can't see anything.
This is an issue when copying in formatted text.
I'll experiment to see if it's something to do with "blackend", which is rather old. Xenforo now has a built-in dark mode we could try switching to, but I suspect the problem would remain.
Maybe I can disable the color bb code

Section 8.5:
e.g. MARIA\THORAX \LEFT\1 would be a valid identifier
