This started happening recently. When I click the link that says something like "View 39 Quiz attempts (16 students)" the next page says "Nothing to Show". I tried setting up a 1 question quiz with one attempt only allowed (to test it) but the same problem happened.
We have no expertise here to modify scripts, html etc etc and don't even have access to our Moodle server. Does anybody know of a simple solution? (e.g., with our last bug of no text editor appearing - a simple theme change fixed that one).
