The WP-Latitude plugin works sweet, but the widget styling does not display correctly. Upon closer inspection the block is missing <li>…</li>, so go to the Dashboard and navigate to Plugins, then click the “edit” link next to WP Google Latitude.
Next find the line that reads, echo “<!–WP Google Latitude Start –>\n”; and insert echo “<li class=\”block\”>”; directly below it. Then find echo “<!–WP Google Latitude End –>\n”; and insert echo “</li>”; directly above it. Save and job done.
