Chat is not working in all site (multisite)

Hi there,
I have embedded chat plugin in multisite. But unfortunately it is not working in all of the site.
In http://legiontraining.staging.wpengine.com/ it is working fine
But I cannot see chatbox in http://legiontraining.staging.wpengine.com/members/
Can you please look at this issue? You can signup for login credentials. But for admin credentials, please tell me where do I send it.

Thanks
