Valid OAuth Redirect URIs

I read you document on how to enter the Valid OAuth Redirect URIs. This is what I put “https://kaypedals.com/account/facebook/int_callback” is this format correct? secondly your instruction is saying to disable the “Use Strict Mode for Redirect URIs” but facebook wont allow you to do that. When testing the message I’m getting is “URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs.”
