Social Share buttons not showing

Hi,

I'm trying to get the social share buttons onto my website (FB, linkedin & Twitter), I believe I've followed all of the instructions and have used your example of this website for positioning. I'm not sure why they are not showing. See attachment for the module settings. I'm pretty sure I got the installation and configuration correct and I've created the necessary apps.

I'm not a developer so I'm a little behind the curve...

Any thoughts?

Thanks

Paul
