Comment from MDLQA-501:

During the preview on step 2 above, editing a question in the preview, I was able to see the edit page but when I went to save the edit I got this error-

Sorry, but you do not currently have permissions to do that (access question edit tab questions)

More information about this error
Stack trace:

• line 379 of /lib/setuplib.php: moodle_exception thrown
• line 3200 of /lib/questionlib.php: call to print_error()
• line 1562 of /question/editlib.php: call to question_edit_contexts->require_one_edit_tab_cap()
• line 62 of /question/edit.php: call to question_edit_setup()

However, when I went back to continue the preview, the edit I had made was saved.

The other steps passed except for "edit and save as a new question" gave the same error as above even though the new question was saved in the question bank.

I am not sure if the correct behavior is to also add that question as an additional question to the quiz since the teacher is in preview mode.

When I went to edit a question, not in preview mode, I got a blank screen and a 404 file not found error and a weird double url:

http://qa.moodle.net/http://qa.moodle.net/mod/quiz/edit.php?cmid=60&category=7%2C78&lastchanged=5

However, when I went back the edit had been saved.
