Thanks for this great module, i try to install but it doesn't seem to work for me :

I have multisite installation

sites/all/modules/fb/facebook-platform
sites/all/modules/fb/facebook-platform/class
sites/all/modules/fb/facebook-platform/client
sites/all/modules/fb/facebook-platform/doc
sites/all/modules/fb/facebook-platform/facebook.php
sites/all/modules/fb/facebook-platform/facebookapi_php4_restlib
sites/all/modules/fb/facebook-platform/footprints
sites/all/modules/fb/facebook-platform/php4client
sites/all/modules/fb/facebook-platform/test

in my setting page
sites/alibaba.ma/setting.php

require_once "sites/all/modules/fb/settings.inc";

themes/fb_fbml

my website url
www.alibaba.ma
my application
http://www.alibaba.ma/node/1657
My facebook app

In the facebook module i see two mysql file

I read facebook documentation, and i need some help on how to set the module / url callback, an example with some screen images will be helpful for people like me :)

Thanks for your great job
