Here's my problem.

When I am editing someone's questions, I can preview the Latex with no problem. enter image description here

But when I am editing someone's answers, I can't preview the Latex. enter image description here

I am living in China mainland and my colleague has the same problem, he couldn't preview the Latex in the answers too.

  • $\begingroup$ yo, can you plz consider cropping the images to make them smaller in the future or use a format that uses less memory. some of us still use windows 97 here... $\endgroup$

    $\begingroup$ I think this is just your computer being slow, not a bug. occasionally happens to me too, as i pointed out, i am using an antique. $\endgroup$

    $\begingroup$ @Lost1 So basically I just have to wait? But sir, I have been waiting for 30 minutes and still nothing happen. Maybe it's because I am living in China mainland? My colleague has the same problem, he couldn't preview the Latex in the answers too. $\endgroup$ Jan 13, 2014 at 15:21

    $\begingroup$ It seems that some people have experienced problem when using MathJax in China before: meta.math.stackexchange.com/questions/2848/… and meta.cstheory.stackexchange.com/questions/1506/… (Maybe you will have more luck to find a post having some reasonable suggestion how to solve this, I did not find anything immediate.) $\endgroup$ Jan 13, 2014 at 15:41
  • $\begingroup$ On the other hand, as you only have problems when editing posts (and not when viewing them), it might be an entirely different problem. $\endgroup$ Jan 13, 2014 at 15:43
  • $\begingroup$ MathJax rendering should all take place locally, so I don't think your location (or GFW) would be causing this. Have you tried checking for updates to your browser / OS? $\endgroup$

    $\begingroup$ @AlexanderGruberI think it's GFW's problem, cause when I am using VPN I have no problem previewing Latex in answers $\endgroup$ Jan 14, 2014 at 10:28

This has already happened with me, follow these steps:

  1. Check your list of add-ons, maybe there is some which is blocking mathjava (for instance Ghostscript, adblock,...).

  2. Maybe you are using a proxy, maybe you have to disable it.

  3. Go to preferences and check your cookies police.

  4. click in the left of the address bar, there is a botton where has the site information, maybe you have to unblock the page.

  5. If anything above worked, change your browser, there are a lot of them (Firefox, Opera, Chrome, among others).
