White blank page, but...

There's another extension on your site that's also trying to load the FB Javascript library. You can see this at the bottom of your HTML with the FB.init({appId:' 13... call. Can you disable this function call? Calling the Facebook library twice on the same page can be problematic. If you can't, we can tell you how to remove the line from our code easily. Both init calls are using the same App ID, which is a good thing.

Other than that, a white page generally indicates a PHP error. If you can let us know what that error is, it would help us narrow the issue down. For more info how:

Thanks

You'd have to contact the Ninja group to figure out why there's a Javascript error in their module. Facebook Connect heavily relies on Javascript to function, and errors in other extensions can prevent these libraries from functioning.

Good luck, and let us know what you find!
