Facebook post social icon not showing

hi,
I've noticed that the post social icons at the end of the posts in my site (http://www.esseci.musicselection.it/mostre/al-primo-sguardo-opere-inedite-dalla-collezione-della-fondazione-cassa-di-risparmio-di-padova-e-rovigo/) have some problems showing... in particularl that one of facebook...sometime it appears much more other times it doesn't and I get an all.js error in the chrome console.

Is there some problem with the theme?
This is a featured of the theme and even if I disable it (what I wouldn't want to do), I still get the all.js error.
Is there a solution?
thank you

Hello,

I can't see the problem with the social icons (and also can't see any js error in the console). Did you solve the issue?
