My tech gave me a "sandbox" term so I could tweek my course over the summer try to make it more user friendly for me and my students. However since I imported my content from the last school semester all assignments are uneditable because "due date in in a closed grading period" but I also cannot change the due date. I also cannot create new assignments for the same reason.
I did import and remove dates from items imported. Help would be appreciated I want this semester to go a lot smoother then last year as I have a lot more on my plate and need one less thing to worry about.
