Facebook Create New App Error - "should not contain protocol information."

Question

I am trying to update/create my app's "app domain" but it keeps throwing this error:

Error

App Domains: http://www.example.com should not contain protocol information.

Whereas I am 100% sure that my website doesn't have any OpenGraph meta tags.

Answer 1

Remove the http:// part

Try only www.example.com or just example.com.

It worked for me.

Answer 2

Just remove http:// I had the same problem, Initially I used to enter http://www.example.com and facebook caused error. But when I used just www.example.com by removing http:// it worked.

Also if you are not using secure server like https://, you need to tick sandbox and specity url in mobile native too.
