I'm seeing [Math Processing Error] all over this site today. Is there a bug or is this problem unique to me? How do I fix it? Thanks.

$\begingroup$ I'm also seeing this everywhere on the site with Chrome, but it seems to work with Firefox $\endgroup$– user9733Commented Feb 10, 2012 at 15:28

$\begingroup$ I was just googling the same thing. I have the same problem with Chromium 16, in linux. $\endgroup$– Bruno StonekCommented Feb 10, 2012 at 15:42

6$\begingroup$ It means crap got in your browser cache. Shift+Refresh forces your browser to pull JS and other stuff anew instead of getting them from the cache. $\endgroup$– J. M. ain't a mathematicianCommented Feb 10, 2012 at 15:48

$\begingroup$ It also happened to me in Chrome (not Firefox) and Shift+F5 (which is apparently Fn+F5 on my HP laptop) works. I have no idea what the issue was. $\endgroup$– anonCommented Feb 10, 2012 at 19:18

Per popular demand:
One of the first things you should do when MathJax is crapping out on you is to try a hard refresh, which is executed by holding your Shift key and then clicking the Refresh/Reload/whatever button in your favorite browser. Browsers usually cache stuff like images and JS bits to ease the task of loading a page. Since this cache is sometimes prone to getting crap on it one would sometimes want to do a hard refresh so that the browser is forced to pull stuff from the servers instead of from its cache.
The more drastic method is to do an actual cache clear (see your browser's help file for details) and restart. If all else fails, consider dropping a line here on meta, or for really severe problems, the MathJax team.

2$\begingroup$ This doesn't solve it for me. I see the formula for a second but then the error jumps and the formula disappears. $\endgroup$ Commented Jun 5, 2019 at 12:11
