Hi all,
It looks like MathJax has stopped working. Every equation is on a separate line:
It is the same pattern for all the opened topics. Another example:
I have no non-supported plugins installed:
I also tried to cleanup and rebuild the app.
What could be the issue?
I also noticed that there was a [RTL fix](https://github.com/discourse/discourse/commit/27f7bd427365307ddaca511632a6e21821f7ddc6) lately, could this be the reason?

👋
I have no repro with latest discourse and discourse-math, using the following test code and a RTL locale:
```plaintext
$$
\hat{H}\Psi=E\Psi
$$
```
Can you give me a better repro please ? Also try `/safe-mode` to disable current theme to ensure nothing is altering this.
Last, but not least, check your browser console, my bet would be that you will find a js error preventing mathjax to do its conversion.

Thanks for your reply!
have you tried one-liner equation? it looks like you showed only the multi-line equations. For one line equation is should be wrapped with one dollar sign `$` and with extra words, something like: `היי $y=x+5$. זאת בדיקה`.
Multi-lines equations work just fine 🙂, the one-liners are the problem.
I checked the DevTools but no errors there. The console is clear.
What is `/safe-mode`?
Also I have tried to switch back to the old theme but I get the same error:
Thanks again!
**EDIT** : Could someone please verify that it is a problem from my side so I could act accordingly? It’s impossible to use my website now 😕 Thanks you all.

Try searching here for info on [safe mode](https://meta.discourse.org/t/53504?silent=true).

Thanks for the reply.
I have entered the [safe mode](https://meta.discourse.org/t/53504?silent=true). At first I checked all of the three available options but it does not tell me where the problem is because then I don’t have MathJax. Then I tried to check only the first two options (without checking the “Disable all extensions” checkbox). In that mode, I still facing with the same situation (equations wrapped with one `$` break, as shown before).
Thanks again.

I doubt this is that RTL fix, but the wrapping fix @Johani made in mathjax may not be accounting for inline math, only block form

Thanks for the reply Sam.
So what could be the problem? Any ideas? 🙂

I found out where the problem is coming form. There is a [new commit](https://github.com/discourse/discourse-math/commit/9615034d78f7eaeee7038ec491423791ba4f5196) in the discourse-math plugin that add a new attribute ‘math-container’.
In the dev tools I see:
If I checkout this attribute, It will work:
