fecabook issues

I need help with facebook. i inserted the key and all but when i test i get this error message:

Configuration errors:

To fix this error, please set your Canvas Callback URL in the application settings editor. Once it has been set, users will be redirected to that URL instead of this page after logging in.

What am i doing wrong here?

I thought it was a defect and it will be fixed on 7.1?

Hello, please go in your Fb account and enter your site calback url like this :

http://your_site.com/modules/?r=facebook_connect/login_form
