I have a quiz (Moodle 3.7) which was inherited from previous year (previous moodle). It seems that the current quit has inherited the attempts from last year. I can therefore not edit the quiz:
> You cannot add or remove questions because this quiz has been attempted.
The quiz is open ended and for informal feedback only. I therefore did not put in an end date. That's probably why the attempts survived the Moodle yearly reset. In an attempt to get round this, I have assigned the quiz an end date/time, which means that the quiz is now closed. This did not help. I then regraded the quiz. This didn't help either.
I'm stuck ...
Anyone knows how to get rid of the attempts of previous year(s)?
