When viewing equations on this site, I see only LaTeX markup. Why are equations not rendering? Javascript is enabled on my browser, so MathJax should be working?

Using Chrome on Mac.

What happened to my comments which were done (still) on MSE? –  Git Gud Aug 27 '13 at 17:50
 
@Edward Do this to create a bookmark that renders the code when you click it. –  Git Gud Aug 27 '13 at 18:01
 
@Git Gud Thanks! However, the bookmarks don't work for me. I tried the various solutions robjohn gives. Even clicking his javascript-launching links on this page doesn't render the bit of test-markup appearing on the page, so this would not seem to be the problem... –  Edward Newell Aug 27 '13 at 18:14
 
Maybe rebooting your computer helps... –  draks ... Aug 27 '13 at 18:35
 
It works now... I didn't even reboot since the last try, nor even closed the browser nor navigated away from the page (although none of these things had effect earlier). –  Edward Newell Aug 27 '13 at 23:26
 
Feel like deleting this question? "Mathjax doesn't work" "Oh wait, now it does" is unlikely to help future visitors. –  Douglas S. Stones Aug 28 '13 at 15:28
 
In the last couple of days this has hit me too in all browsers I've tested: Safari, Chrome, Firefox. There is a connection timeout when loading things from cdn.mathjax.org. After a long time, the page is rendered without rendering the formulas. The Javascript console in Chrome shows "Failed to load resource". Safari says "Failed to load resource: The request timed out.". –  lhf Aug 28 '13 at 16:36
 
@Douglas Maybe, but not yet. –  Edward Newell Aug 29 '13 at 0:50

I am having the same problem. When I open the Javascript console, it says" Failed to load resource: the server responded with a status of 400 (Bad Request) cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML Uncaught ReferenceError: MathJax is not defined cdn.sstatic.net/js/mathjax-editing.js?v=6da1b6cfe19f:3" –  Sujaan Kunalan Aug 29 '13 at 15:58
 
I'm having this same error. What on earth happened? –  Cameron Williams Aug 30 '13 at 1:48
 
\multicolumn does not work in the MathJax of stackexchange. –  Felix Marin Sep 2 '13 at 16:21

In Chrome, open the menu (usually on the right hand side next to the URL field) and select "tools" and open up the "Javascript console".

In the same window, then load the Math.SE home page. You should see something like this

Please edit your original question above to include either a screen grab of the error messages you see, or copy and paste the messages from the javascript console as text/code into your original question.

Since MathJax is working for most of us, this is likely a configuration issue on your end. We need more information before we can troubleshoot the error.

Thanks Willie. It seems to be working again. I'll post such errors though if this is a persistent problem. –  Edward Newell Aug 27 '13 at 23:27

@lhf: unfortunately, if there's a connection time-out error, there's nothing you or StackExchange can do to fix it, except maybe possibly switching to a different DNS server if you suspect the problem to be caused by DNS resolution. –  Willie Wong♦ Aug 28 '13 at 19:43
 
It is not a DNS problem. Other sites were ok, even www.mathjax.org. After a few hours it went back to normal. Let's hope it stays that way. –  lhf Aug 29 '13 at 0:38
 
I'm getting a Blocked loading mixed active content "http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML" error in Firefox while using HTTPS Everywhere. –  l0b0 Jan 8 at 17:40
