 * I’m using Simple MathJax with Learndash and it has always worked extremely well.
 * In order for MathJax to work inside quiz questions we have to add this code snippet:
 * [https://www.learndash.com/wp-content/uploads/latex-snippet.txt](https://www.learndash.com/wp-content/uploads/latex-snippet.txt)
 * However with V2 of Simple MathJax we now get an error:
 * > Uncaught TypeError: Cannot read property ‘Queue’ of undefined
 * Which clicks through to the line:
 * MathJax.Hub.Queue([“Typeset”, MathJax.Hub]);
 * (In the second jquery block in the code snippet.)
 * Simple MathJax V1.1 still works fine. Please let me know if you can think of 
   any change in V2 which is causing this error. Please can you suggest a fix?
 * Thank you.

 * The v2.0 of the plugin defaults to MathJax v3 which has a different API. You 
   can set the plugin to use MathJax v2 in the preference pane until you find a 
   way to upgrade your own code to be MathJax-3-compatible.
