I'm running a 2 colume blog, main content and sidebar.
When i use the "share buttons" then it removes the color of the sidebar and make it all white.
my site is http://www.david-sylvest.dk
You can it happens on every page, when i activate the plugin. - It's activated right now, go see for your self :)
You can see the gray color a second after the pageload and then the websites "blinks" and then its all white.
I really do however love the plugin! - great work!
