@cristian-xubliminal: For Dashboard widget, you need to have a valid addthis login and publisher id configured in the plugin’s Basic tab. After that, check the “Advanced” tab to enable “Show analytics in admin dashboard”. Now if you check your Admin Dashboard, you will be able to see the analytics. Let us know if you need further assistance.
@divavocals The dashboard widget is fine and working. If you are having issues in your installation, it might be a different, independent issue and can be resolved only if you can provide more information.
