AddThis not working on WP4.0

I have activated the AddThis plugin, but it doesn’t seem to be able to place icons below posts. Here is an example of a single post page where I would expect to see icons (at the bottom only) but none appear.

If you do a search of the source code of this page you’ll see that the javascript file is linked to, but there is no mark-up for the buttons.

On the other hand, the widget is working just fine.
