Ultimate Facebook integration for individual sites in Multisite Multi Network

Hi,
In my multisite/multi network environment hosted with greengeeks, I currently run my own site nettgut.no and my wp client higho2.no
My Ultimate Facebook doesnt seem to run properly because although I added all necessary data,
in the control panel Ultimate Facebook settings it still reads "This step must be completed before using the plugin. You must make a Facebook Application to continue.". Also, the facebook buttons are not visible on nettgut.no/blogg

If you could please guide me on my site with the proper integration, I will also be able to replicate it for my client.

My site is nettgut.no, my facebook app ID:

(nettgut means net lad in Norwegian:slight_smile:
Thanks in advance
