thanks Micheal, your turnaround is better than some paid support

I've applied the fix (more like ran diff on the files and patched mine with the few new lines of code), unfortunately it makes no difference for me. If I'm not logged in to FB I don't see any faces, and when I'm logged in I see only mine.
What's the normal behavior when one is logged in? show all faces who also Liked or only those of friends who also Liked? (I know this is not a question for you proper).
If the latter, it may be because I have no "friends" amongst the other Likes.
Still, you probably don't have any of them as friends either, so how come you saw the faces? there, I busted my own speculation.
I will update to the latest nightly soon, hopefully that's the key to solving this.
