I do seem to have to a problem with starting your All Facebook Plugin on Wordpress?

I started with an App on Facebook called Ongoro Shop and from this App
I started a fanpage called facebook.com/ongoro.wine

The website is http://www.ongoro.co and I used the WPMUDEV's Dixie theme.

But I can't seem to get your plugin about Facebook to get working. In Wordpress I keep getting the comment from your plugin - Please provide correct Facebook API settings.

Many thanks for you guys trying to help me.

Kind regards

Herman Fouche
