For Forums that not associated to the course, which open for everyone. Text “You have to enroll the respective course!” is displayed, if topic is associated with course, this text has additional line “Go back to ”. In first cause (if this is common topic for everyone), topic must be displayed. Authentication limitation must be managed by bbPress module. If topic is associated with course, current message is correct. * Plugin Contributor [Lewisst](https://wordpress.org/support/users/tungnx89/) * (@tungnx89) * [1 year, 3 months ago](https://wordpress.org/support/topic/learnpress-bbpress-integration-error/#post-18305711) * Hi borisadlivankin, Yes, Did you enable “Restrict User” on course, if enable it will show that message, if user haven’t enroll course.Thanks. * Thread Starter [Boris Adlivankin](https://wordpress.org/support/users/borisadlivankin/) * (@borisadlivankin) * [1 year, 3 months ago](https://wordpress.org/support/topic/learnpress-bbpress-integration-error/#post-18305785) * Hi Lewisst, The problem is – this forums is not defined to any course. I have fixed this problem when disable Restrict User option in Forum tab on all courses. I have asked to content author – she was agree this. But, this is not correct behaviour. Now all forums is open for everyone, even they didn’t purchase any course. * Plugin Contributor [Lewisst](https://wordpress.org/support/users/tungnx89/) * (@tungnx89) * [1 year, 3 months ago](https://wordpress.org/support/topic/learnpress-bbpress-integration-error/#post-18305919) * Hi borisadlivankin, We don’t know reason it error on your site.
