Actually the old code stopped working a while back for reasons 'm not sure, hence the reason I opened this ticket.
You are however right about revisiting the Addthis code. Apparently there an additional code to place at the needed location of the article template. See screenshot from Addthis
Advice where to place the code:
<!-- Go to www.addthis.com/dashboard to customize your tools -->
<div class="addthis_inline_share_toolbox"></div>
It's currently floating at the bottom of the page as you can see
