Can't Load URL

I’ve spent the last hour and a half trying to get this Social Importer to work. It’s killing me! I’ve been working on the website most of the day and figured I’d get this last thing in and I can’t get it to work at all. I’ve created the facebook app, real straight forward. I add the “app id” and “facebook app secret” and it just never works. I keep getting this:

“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 tried creating a new app several times and tried adding more urls and ip address and NOTHING works, it always comes up with the same error. Please help!
