Im having að problem displaying map with my track.   It did for a few days after installing (but very slowly, bad performance), but now no maps are shown.  The GPX module does display all tracks (google point marks).  

See http://www.kayakklubburinn.is/index.php/frodhleikur/tracks/viewtrack/1-

I can see (by pressing F12) an error message "Uncaught TypeError: google.load is not a function".
