I have issue with Facebook signup and login. I tried everything.
Error is coming " 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. "
I know it is something related to domain setting which I have already done and tried with different settings. But still not working. I am attaching screen shot. I do not know what is issue.
I also tried to fix by youtube video. There is no official Discourse video but just some random youtuber. But it is not working either. Any step by step instructions available, please let me know.
