Ive tried using dataform to add an activity where files can be uploaded on a students behalf as per here:
But I cannot get it to work.
Nothing appears when clicking add, cannot pick users etc.
The poster in that thread sent me a preset as well that I used but no such luck.
I turned on debugging and get an error as in the attached screen shot.
I have attached the preset aswell
I am using modle 3.03 and PHP7 if that helps. Also using the latest download for dataform on the moodle plugin site
Any advice would be appreciated.
