I was getting this error Can’t Load URL: The domain of this URL isn’t included in the app’s domains”
I was following that TUT which i thought was from your site. As you can see in the pics it has Use strict mode for redirect URI’s set to NO.
In the facebook settings that is now set to YES and you can’t change.
I went to another app of mine where it is set to no, entered the id and secret and I was able to use it straight away with no problem.
i assumed it was because it wouldn’t let me select no.
