Answer 1

Probability, wrong configuration on FB developer dashboard or blank in App Domains Textbox or have you changed a URL's of an existing App?

You should recheck again under Facebook.

1. Check correct App setting

2. Add App Domains in App Domains Box Check

3. URL and path to your development environment

You can reference in Answer1 and Answer2

I'm not sure this step is related with yours. But, I tried to test according to your error message.
