Moodle 2.1.2.
I've been bitten by this glitch now and can't find my way out of it. Basically, when I try to manually back-up a specific course, I immediate get the error/activity_task_coursemodule_not_found error. "More information" takes me here: http://docs.moodle.org/21/en/error/moodle/activity_task_coursemodule_not_found
I've followed the suggestions on that page (I did see five "instance=0" instances and deleted those rows as explained in the instructions), but to no avail. The backup error is still present.
Other courses seem fine, but not the one I need to backup. Isn't that always the case?
Any other ideas?
