I have an assignment that requires an uploaded file. I created my own grading scale or completed/not completed. When I go the grades page I get the following error:
Warning: Invalid argument supplied foreach() in .../mod/assignment/lib.php on line 254.
Any ideas? I've narrowed it down to the assignment with the uploaded file. Have I created my custom scale incorrectly?
It seems like it should be pretty easy - any suggestions of things to try?
