Debug script on buddypress. Do you know how to fix?

I was uploading a doc from the front end on BuddyPress using updated theme BuddyBoss 2.0 with the BuddyBoss Social Learner child-theme. The script is here:

Warning: Invalid argument supplied for foreach() in /home/content/p3pnexwpnas10_data01/95/2850095/html/wp-content/themes/boss/docs/single/groupnav.php on line 6

Thank you,
Ben
