I installed the WP Chat module from here on my Buddypress site about 10 days ago and all worked well. Then I noticed that a new update had been released and I updated. After the update everything still seemed fine except the 'Available' badge is not showing in individual profiles any more. It still shows up at the members-loop / directory listing but I can't get it back on the profile page where it's needed. I haven't updated my theme at all during this.
My confirg is:
Theme: BuddyBoss v 3.1.7 (running child theme).
