Fatal Error After Update to 2.3

After updating the theme and all the plugins, everything works fine until I enabled the "Assign Free courses to students on account activation" option. After enabling this, people were not able to register on the site and I get the below error message   Fatal error: Uncaught Error: Unsupported operand types in /home1/fmurad/public_html/beat-tweaks.com/wp-content/plugins/vibe-course-module/includes/bp-course-functions.php:1451 Stack trace: #0 /home1/fmurad/public_html/beat-tweaks.com/wp-content/plugins/vibe-customtypes/includes/tips.php(1746): bp_course_add_user_to_course(76, false) #1 /home1/fmurad/public_html/beat-tweaks.com/wp-includes/plugin.php(524): WPLMS_tips->wplms_activate_free_courses(76) #2 /home1/fmurad/public_html/beat-tweaks.com/wp-includes/user.php(1691): do_action('user_register', 76) #3 /home1/fmurad/public_html/beat-tweaks.com/wp-admin/includes/user.php(184): wp_insert_user(Array) #4 /home1/fmurad/public_html/beat-tweaks.com/wp-admin/user-new.php(116): edit_user() #5 {main} thrown in /home1/fmurad/public_html/beat-tweaks.com/wp-content/plugins/vibe-course-module/includes/bp-course-functions.php on line 1451   Do I need to Disable auto allocation of free courses for this to work or does that not have anything to do with it?  I also have some code related to this in the wplms_customizer.php file from a previous help topic. add_action('bp_core_activated_user','wplms_activate_free_courses',99); // Runs when user activates his account. add_action('user_register','wplms_activate_free_courses',99,1); function wplms_activate_free_courses(){ if(!is_user_logged_in()) return; $user_id = get_current_user_id(); $course_ids = array(2139); //Array of course ids you want user to get access to on account creation. foreach($course_ids as $course_id) bp_course_add_user_to_course($user_id,$course_id); }   Should I remove this code:
