I am using the PHP from this tutorial (http://www.jacobtomlinson.co.uk/2013/03/17/using-the-addthis-share-buttons-wordpress-plugin-in-a-custom-theme/) so I can place the share buttons where I want in my template.
However, the share buttons are not showing up and when I turn on WP debugging I get this error:
Notice: Undefined variable: button in .../plugins/addthis/addthis_social_widget.php on line 448
Can this PHP error in the plugin be fixed in an update please? I am using the latest version of the plugin (3.5.3).
