Hi @privatedanish,
I am transfering your topic here in the correct theme.
To answer your question, we have released a new version of Gwangi along with the Grimlock for BuddyPress update. So updating your Gwangi theme should resolve the issue.
As a rule of thumb, when any of our “Grimlock” plugins gets an update, please always check for new theme updates as we often release both at the same time to avoid that kind of issue.
Best regards,
