Andrea,
It's likely not a Chrome issue, but what extensions/add-ons you have installed for Chrome. Please check your add-ons for anything that may block social networks or virus/firewalls that may be doing so as well.
Beyond that, I'd try using Chrome on a different computer to see if that changes the behavior.
Please let me know if that helps. There likely isn't anything we can do fix it on our end.
Thanks,
Alex
