Share buttons not displaying

Not too sure if this is due to an update but my share buttons have vanished from below my posts?

When i check the source I can see them there?

They just aren’t displaying, any ideas?

I can access the js file, so that’s not the problem…

src="//s7.addthis.com/js/300/addthis_widget.js#pubid=ra-51196f2443671312"
