If you choose the weekly format for your course modules, you may need to update the dates for the current term. Click on the admin gear in the upper right corner of your course, then choose Edit settings. Locate the field labeled Course start date. Use the pull-down menus to set the day, month and year of the term's start date or use the calendar on the right. Scroll to the bottom of the page and Save changes.
Note: We've also seen a few courses that have a course end date enabled, set up to end the course whenever the weeks represented by the number of sections in the course have elapsed. Be sure to uncheck the Enable box associated with the Course end date if it is checked in your course. If additionally you see the option highlighted below, be sure to uncheck that box as well.
This function solely affects administrative settings that we do not intend to use, so disabling it will result in less confusion all around.
