facebook application only accessible by my user account

I am developing this small facebook iframe app. I am using .net's facebook developer toolkit. It works fine for me wit开发者_如何学Goh my user account. Though when I tried testing it through a friend's account (several friends actually) the facebook API doesn't seem to get populated with any information. My application is still in development stages.

Any ideas? This is really strange!

Edited : Ok this is resolved, I've updated to facebook developer toolkit version 3.0 (it is currently in beta, yet seems to be quite stable now)

Thank you all for your help!

Check that 'sandbox mode' isn't set, under Advanced Settings.

If you're using an iframe app, install Firebug http://getfirebug.com/ and have a closer look at the communications going back and forth.

Have a look at the error logs on your server - is the correct data being requested? Is it being served up?

View the source of your app's frame. In your case, it seems you have

<fb:redirect url="http://www.facebook.com/login.php?api_key=[xyz]&v=1.0&next=default.aspx"/>

That's an FBML tag, but not being parsed by Facebook. I suspect your app is set to be an iframe but maybe should be an FBML app. [update] If you need it to be an iframe app, you need to replace fb:redirect with the javascript call

window.open('http://www.facebook.com/login.php?api_key=[xyz]&v=1.0&next=default.aspx')

It might be that your app hasn't been reviewed by Facebook, check https://developers.facebook.com/docs/apps/review
