I'm using 2.2.2+ (build 20120405) with custom plugins by Open University to create quizzes. I've just upgraded from 20110726 in the last week.
I've run into trouble with one quiz. Going to Quiz administration -> Edit settings -> Overall feedback -> Grade boundary, the input is locked. Following from this, if I add anything to the 'Feedback' textbox and try to save I receive an error "You must fill in the feedback boxes without leaving any gaps."
I've tried the same on other quizzes. The inputs were not locked, but if I save and return to the 'Edit settings' page I see that my grade boundaries and feedbacks were not saved. Previewing the quiz also shows this.
I'm certain I could do this before the upgrade, in fact I still have a quiz which I created before the upgrade and still has these boundaries set up.
I've had a good look at a similar problem and tried a few things mentioned there http://moodle.org/mod/forum/discuss.php?d=180728
- I have checked that Site administration ► Plugins ► Activity modules ► Quiz ► Maximum grade is equal to something non-zero (it was and continues to be 10).
- I have tried a whole bunch of different browsers with and without addons.
Thanks,
Robin
