I started using Taskchain for my Hotpots, but I'm finding that when I set completion tracking for "Student must receive a grade ..."
(1) I get an error message "An internal error occurred in the completion system (System administrators can enable debugging information for more detail)". I tried enabling debugging information but nothing's showing.
(2) completion is not marked. Because the activity completion is not marked, the next activity which is conditional on completion is not accessible.
(3) When I set access restriction (see attachment) it does not show. UPDATE: After I got rid of the access restriction in the following activity (19.5) the access restriction information for the Taskchain (19.4) started showing.
