We are unable to (a) delete a question (b) change marks for a question in quizzes of a particular course only. We are able to do the same things in other courses. Tried purging cache, but it does not work.
Note that the quiz has NOT been attempted.
On clicking "delete" on a question, we get this error on Developer tools console:
moodle-core-event: Global event published: FORM_ERROR yui_combo.php:5828:31moodle-core-event: Global event published: BLOCK_CONTENT_UPDATED yui_combo.php:5828:31This course uses questions that use MathJax and we suspect something wrong with MathJax.
Given below is MathJax configuration:
MathJax.Hub.Config({ CommonHTML: {scale: 60
},
config: [ "Safe.js","TeX-AMS_HTML-full.js"],
extensions: ["TeX/tex2jax"],
errorSettings: { message: ["!"] },skipStartupTypeset: false,
tex2jax: {inlineMath: '@#','#@',
displayMath: \[','\\]'">'\\[','\\]',
preview: "none",
}
});
