Not Showing Nicely

Firstly, what does the option “Disable Socialite” do? I can’t work out what the socialite feature is.

Secondly, http://capetowninsider.co.za/kgalagadi-transfrontier-park-chevrolet/ it seems to get stuck on the social images. Are there any specific settings with W3TC that need to be configured?

Any help is appreciated!
