It looks like LaTeX works if you don't use exponents...

\( a \le b \)

... but not if you do use exponents:

\(a \le b^c \)

@peterdrake I find it hit and miss on my browser. And the one with the exponent rendered, the other didn't. ;) Now both.. uh.. well, it changes constantly. Might hit up @freemo to check if this thing works nicely. :P

This has to do with the Content Security Policy interfering with self-hosted scripts. There are good reasons for doing this - in particular, some types of files users upload, like SVG images, can contain arbitrary JavaScript. I think the MathJax code just needs to be added to whatever whitelist exists for necessary scripts, but I'm not sure how to do that (and it's probably @freemo who has to make the change anyway).

I tested this by disabling CSP in my browser (Waterfox preferences security.csp.*) temporarily - but I do not recommend this as a permanent workaround for reasons outlined above.
