Hi Vibe,
The Forum on a Course page isn't accessible to logged out users. How to make it accessible to them?
a. Uncheck the WP Admin - LMS - Settings - Course Forum privacy
b. Make sure the BBPress forum you create is not set to private.
Thanks for this. What if I don't want unlogged in users viewing the forum? When they click it instead of redirecting them to the homepage, is there a way to show a 404 error page or something that tells them to register before proceeding?
Set the forum as private. Unfortunately, you'll need to search for a third party BBPress plugin to add this.
