Hello,
Just found this thread after googling "moodle any other way to delete a quiz?"
I'm having a problem deleting one particular quiz. Think I'm using moodle 1.9, but not an admin so not sure.
Turn editing on, click delete, confirm that I'm "absolutely sure" that I want to delete it, then nothing... until this: Fatal error: Maximum execution time of 180 seconds exceeded in E:\Moodle\server\moodle\lib\dml\mysqli_native_moodle_database.php on line 1080
Same result every time. This is the only thing I've not been able to delete in many years of using moodle.
I can adjust and save the settings (but one?) of the quiz and edit the quiz itself (I've deleted all the questions), just not delete it.
Here's a possibly related fact. When I created the quiz I had "Separate groups" and "Group Project" (my name for the default grouping) selected in the course settings. I had been (vainly) trying to get some group functionality (like applying scores to all members of a group). So the quiz I'm trying to delete was automatically made into a "Group Project" assignment. I.e. on the class home page it shows "(Group Project)" next to the assignment. Although I can change the "Group mode" for the quiz settings to "No groups" and save it, it always shows up on the home page as a "Group Project".
Any advice would be appreciated. Also, if a group of moodle commandos would descend on our IT dept and upgrade our moodle, that would be nice as well.
