Facebook PHP SDK - Login helper returns error
问题 i have created a app witch are using facebook as a login opportunity. My APP worked public fine 1 day ago, but today it started getting this error when my users are logging in: Graph returned an error: Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings. My code looks like this: <?php require 'vendor/autoload.php'; if(!session_id()) { session_start(); }
