In the current Canada, USA, World distributions, you can run either the ajax-dashboard OR the ajax-gizmo on a page, but not both. The reason is that the AJAX requires unique id="ajax...." for each WD variable to be AJAXed .. HTML rules allow only one instance of a specific id="" per page. On the wxindex.php, leave the $showGizmo = false; so the dashboard will have the correct information.
In a future release, I'll replace the ajax-gizmo with a new one (and a modified ajaxWDwx.js script) so that you could run the gizmo on each page (including the one with the dashboard) .. but that's a future release
Best regards,
