Facebook Like Button not showing up

Hello,

My site is Your 90s

This problem has me banging my head against my desk :/

For some reason the Facebook like button is disappearing when I’m logged out of Facebook.. and it no longer shows the number of likes or the ability to sign in and like the posts…

Could it be the side Facebook page feed? Any ideas? Thanks much.

Cheers, Dalton
