I assume that for some reason question.php either isn't calling the respective editquestion.php files or there is something wrong with the editquestion.php files. I don't know if it's supposed to do this (I expect it is), but if I try to go directly to a editquestion.php file in my browser, I get the following error:
Fatal error: Call to undefined function: print_heading_with_help() in /usr341/home/g/o/goahead/public_html/moodle/mod/quiz/questiontypes/multichoice/editquestion.php on line 21
Help! I'm replying to myself here and hoping someone can help me. I've tried everything I can think of and I've searched the forums but I can't find a solution.
