LaTeX Trying to write in LaTex and MathJax not picking up

[giodude]

I'm attempting to use latex to write a question in the physics forum. However, when I click preview to check if the formatting is correct it doesn't reformat to display in its latex form, rather it stays in plain text. Any suggestions on what I may be doing wrong?

I've posted the screenshots of before and after clicking preview below.

Reloaded the page and seems to have been fixed now.

It's a known bug that seems to be hard to fix.

The parser doesn't load on a page update (like when you reply to a thread), only on the initial load. So if there isn't already LaTeX on a page it doesn't render in a new post. Refresh the page to render.

Likewise, it doesn't work in reply preview unless there's already LaTeX. You can fix this by writing some LaTeX, going into preview, and then refreshing (it's a good idea to take a copy of your text first, just in case...).

LaTeX doesn't work at all in the new thread editor. My advice is to compose an opening post in the reply box of a thread with LaTeX, then paste it into the new thread start when you're happy.

The bug is actually worse than LaTeX not rendering. After writing some LaTeX, when you refresh the page, inline LaTeX will be rendered in the text editor itself. The moment you click Preview or Post Thread, the rendered LaTeX will be transformed into garbled text. You won't have the source code anymore.
