Plugin, Module and scripts don't work for me

The Facebook Page URL you've put in there is:
www.facebook.com/liguriasconti

However, I can't go to that URL. When I try, I'm redirected to the Facebook Home page. Do you have some restrictions on that FB Page or is it not public yet? If so, you won't be able to publicize it on your page to the 'public'.

Other than that, things look like they're setup properly, you just need to figure out why the Facebook Page isn't working on Facebook.com itself first.

I hope that helps,
Alex
