Since we turned guest access off for fall 2021 Academic courses, some instructors have reported notices about "orphaned content." The culprit seems to be the Collapsible topics course format, which is erroneously getting reset when guest access is disabled. We have reported the issue to the developer of that plug-in; in the meantime, this workaround seems to fix the issue:
- On the course main page, click the gear icon (Actions menu) and choose Course Settings.
- Under Course format,
- Reset Format to Topics.
- Reset Hidden sections to Hidden sections are shown in collapsed form.
- Click Save and Display.
- Click the gear icon (Actions menu) again and choose Course Settings.
- Under Course format,
- Reset Format to Collapsed topics.
- Reset Hidden sections to Hidden sections are completely invisible.
- Click Save and Display.
