You should check out the example longitude, latitude on the map page 
<!-- location:latitude=+34.06.00,longitude=-75.80.00 -->
'cause it's in an illegal format. From the stats help page 
The minutes and seconds values must be >= 0 and <= 59

Anyway i'd like to suggest Maporama (no registration required) to get your longitude and latitude, keeping attention to convert minutes and seconds to base 60.
