Refused to display… frame-ancestors https://www.facebook.com

Question

I have included Facebook customer chat plugin on my website. It works fine for the first day. From the second day, it\'s not working. I have seen an error message in Google

Answer 1

I think that's not coming from facebook but your website. Your browser refuses to display an iframe from a "bad" source, in this case facebook.com.

Or greenlight any requests from facebook like in this example (which is not the best way to do it, as it undercuts some major protection against XSS):
