Social Sharing not working - Joomla 3 localhost

Hi,
I have installed CjBlog on my local machine to test its functionality before installing on live site. It looks like it will do what we want of it, but I cannot get the social sharing buttons to work. I have set the option on the Integration panel to show social sharing buttons, but when I create an article a dn view it on the site, there are no social sharing buttons visible anywhere.

I am using Joomla version 3 on localhost. Not sure if this is the issue???

Any help appreciated.

Cheers,

Ben
