If your Classes and Assignments have disappeared, your Class may have been auto-archived because it is likely that the class end date is set for a date in the past. Once your Class reaches the end date it will auto archive. You can edit the end date to a date far enough in the future that will cover you for the whole class period and then un-archive the class. Once you do this, all of your assignments will return. You can also manually un-archive any archived classes.
To edit an archived class end date:
1. Select the 'Archived Classes' tab at the bottom of the left sidebar on the Dashboard.
2. Select the specific archived class for which you are looking to edit the class end date.
3. On the class page select 'Details'.
4. Select 'Edit' to edit the class details and change the 'Class End Date'.
5. Select 'Save'.
To manually un-archive an archived class:
1. Select the 'Archived Classes' tab at the bottom of the left sidebar on the Dashboard.
2. Select the specific archived class for which you are looking to un-archive.
3. Select 'Un-archive'.
4. Your class is now un-archived.
