I am receiving this error Fatal Error: Call to unidentified function bp_activity_get() after the update and the students are unable to pursue the course.
Exact Error Message:
Fatal Error: Call to undefined function bp_activity_get() in /home/content/n3pnexwpnas02_data03/37/3152837/html/wp-content/plugins/vibe-course-module/includes/bp-course-offline.php on line 81
Moving the topic in update forum.
The error suggests that the activity component is disabled in your buddypress component, please go to wp-admin->settings->buddypress->components, and make sure the activity component is enabled.
Thanks, this solved the problem.
