# MathJax not working in some cases

I'm not sure if this is the right place to ask this question, but I'm experiencing rather strange behavior of MathJax in Google Chrome. On some stackexchange sites the LateX equations don't render. On Physics I can see only the source code:

However on math.stackexchange.com I can see it perfectly:

These 2 screenshots were taken in the very same browser (Google Chrome under Windows 7) during the same session. Each site is open on different tab - one is working, the other one is not.

When viewing in Firefox, everything is fine. Just Chrome refuses to display equations on physics (and sone other SE sites). Also I tried Chrome on other computers and everything is fine there as well. So the problem must be partially tied to my specific Chrome installation and also somehow tied to certain SE sites (because the same Chromw browser can display equtaions on Math SE).

Do you have an idea why this could be happening?

• Probably a CDN issue, Math.SE uses a slightly newer MathJax version, iirc. Things are working for me, which usually means a CDN problem. Clear your cache and wait for it to resolve itself. – Manishearth Jun 6 '14 at 9:26
• As an aside, the middle two $ are superfluous, you can simply type $\gamma_{ij}g_{\mu\nu}\$. – Kyle Kanos Jun 6 '14 at 13:06
• @KyleKanos You're right. This was just a dummy test, so I used some 2 arbitrary expressions which don't even belong together. – mpv Jun 6 '14 at 13:52
• I observed a similar thing: I was trying to write \left<x\middle|p\right> and it kept "failing to compile" as if \middle weren't a TeX command. While I was confused it suddenly started working again. – rob Jun 6 '14 at 14:23
• @Manishearth Clearing the cache helped. Thank you! – mpv Jun 6 '14 at 19:37
• Hmph. We don't have a [status-at-user's-end] tag. – dmckee --- ex-moderator kitten Jun 7 '14 at 0:20
• @dmckee eh, I think that's usually what status-norepro is for – David Z Jun 8 '14 at 17:14
