Benjamin,
What does your full LocateWidget xml look like?
<?xmlversion="1.0" ?> <configurationlabel="U.S. Geocoding"> <locator>http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer</locator> <minscore>30</minscore> <zoomscale>2000</zoomscale> </configuration> <!-- See Locate widget tag reference at http://links.esri.com/locatewidget

Benjamin,
Are you sure you are editing the XML file that your locate widget is pointing to based on the url in the main config.xml?
Example:<widget label="Find an address" left="100" top="90" preload="open" icon="assets/images/i_target.png" config="widgets/Locate/LocateWidget.xml" url="widgets/Locate/LocateWidget.swf"/>
