Hello,
I've the same problem: http://www.opencrmitalia.com/blog/social-network-tutti-i-dati-del-2013-iscritti-utenti-attivi-fascia-d-eta-paesi.html

Can't see g+ and facebook share button, also if they are setted to appear!

I activated it in frontpage and now it works!

Sorry if I write again,
if I arrive from frontend blog I an see G+ button, but if I reload the page not!

Hello Simone,

So sorry for the delay in getting back to you. I tried to load your page in Chrome and Firefox then reload both of them and the Google+ and also teh Facebook buttons are still there. I can't seems to replicate your issue. Can you please try to do a hard reset on your browser. Hope this helps.

Thanks!
