Google sharing creates bug on template appearance

Hey,

I have a bit of a visual ‘bug’ appearing on my blogpost-pages, (such as this one). By looking at the page in developer mode, I’ve found that the bug is actually an iframe for, what I guess is, my website trying to log on to google for whatever reason.

I’ve deactivated the sharing option for Google+ and have no other Google plug-ins that I’m aware of, so I’m at a loss with what’s causing this weird stripe.

Your help would be much appreciated!
