A few days ago, we’re not sure the exact time, something changed which caused problems when sharing an AddThis WordPress plugin enabled blog page to Facebook. The FB shares do not have the correct page title, description or images. This problem actually affects any page that uses the AddThis code specified in the technical section later in the post. However, we are only going to address the plugin related problems at this time and provide you with a simple patch.
Here’s a quick little patch for the WordPress AddThis plugin. Follow these instructions at your own risk. This patch has only been tested on WP 2.9.2 and AddThis Social Bookmarking Widget 1.6.1. We do not guarantee the patch nor do we take any responsibility if something breaks.
