Facebook Icon disappeared when I reset the hb-theme fb page to mine

Well, I reset now it appears there is just a crappy doc (or something icon). I tried resetting the social link to hb-themes fb for shits and grins… the icon does not reappear.

I have made my site visible temporarily so you can see it. http://www.thebarkingbooth.com. So frustrating!I attached a screen shot. Please help. Thank you.
