I have installed the plugin but I'm unable to find it anywhere on the websites. It's also not in my widgets.
The instructions that you provided:
setting: group -> admin -> group chat Are not in my buddypress
I have settings, general, email profile no other settings (like group) and I am the admin. The backend I see Groups, with all my groups but no chat settings. Where can I find the chat??? It's already activated in plugins.
