I just installed the latest dev version, 1.6 DEV, and I cannot get the new Quiz/Essay to work. I can setup the essay questions and the student can take the quiz but when the teacher goes to correct the questions under the manual grading tab, I get the following error message:
Invalid attempt and question ids
I downloaded the latest version again with the same results. The install went fine, the only things I did was ccreate a course and added a quiz with one essay type question.
I know this was an old question thread but it is the closest one I can hope to get a hint.
I got the same problem for the error message "Invalid attempt and question ids" but it only happen at the second quiz with essay questions. The first one is ok. (ok, now in the system there are only 2 quizs with essay question.)
What should I look for?
