If you are connected to FB as I am --please post here if you are unable to send or receive lives.
When I request them I get the following error message:
"Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings."
This happened before -- was temporarily resolved -- and now back AGAIN!!
