    $\begingroup$ The new version of MathJax seems to be incompatible with my computer (equations are showing up simply as the string of symbols used as commands). Is there any update I should make for MathJax to work? $\endgroup$

    $\begingroup$ I cannot say more on how thankful I want to express to this open source project. Without MathJax, my project WEB interface will almost be impossible to be done within a few days. As a MSE user, I also want to thank MathJax for making this site so great. $\endgroup$

I've gotten this issue twice now, it randomly starts working every now and then. But the MathJax looks like this:

I've tried restarting chrome, clearing cookies, clearing my cache, etc... it seems to work fine in Firefox, but not in Chrome.

This is what the developer console shows:

I'm on Windows 10 running Chrome 52.0.2743.116 (Official Build) m (64-bit) with Javascript V8 5.2.361.49

  • $\begingroup$ The screenshot indicates that your cache is probably not clean since the TeX-AMS_HTML-full.js file is loaded with 2.6.1 in the query string (while it should be 2.7.0-beta). Could you try clearing your cache again and restarting Chrome before trying again? Chrome sometimes doesn't clear cache properly. $\endgroup$ Sep 8, 2016 at 10:35

    $\begingroup$ @PeterKrautzberger Of course! Thanks. Press F12 to open the developer console, then with the console open in the background, right click the reload button (on chrome) and select the "hard reload and clear cache" option - got it working for me. :) $\endgroup$
