I installed the MathJax plugin on my localhost Discourse community. I enabled it in the settings:

But for some reason it does not display the formulas, not in the topics and not in the previous:

The formula I tried:

```
$$\frac{a}{b} \cdot 5 = 5a\cdot b^{-1}$$
```

Discourse is set to be in Hebrew (RTL). Maybe that is the reason?

How to solve it?
