Hi,
when I try to create a new question, the modal pop-up menu comes up but I cannot tick any options; it looks like is disabled (see screenshot)
I am using moodle 3.2
Does not happen at demo.moodle.net, so it must be something specific to your site. Which theme are you using?
i use my own custom made theme. i guess i have to check what classes are used fir the modal in a moodle theme.
