The reason that students can't submit their papers is because the turnitin due date is listed as having passed. When you create a turnitin assignment, you'll need to set the due date for the assignment in turnitin independent of any date you assign to the assignment via Moodle access restrictions.
To do this, go into the assignment (click on the assignment name, not the assignment settings), click on the pencil icon, and change the assignment's due date settings. You can leave the post date settings the same. Post date only affects when the assignment becomes visible for student viewing.
