Hi,

If you do a view source of your page, some javascript functions that should be there to display the googleMaps are missing! e.g.
- function onload_gmap()
- function display_gmap_gmap()

1) Can you please try uninstall the googleMaps plugin and then reinstall the latest version?

2) If after (1) above, it still doesn't work, then can you please temporarily stop the K2 and see if the googleMaps works - this will allow us to see if it's conflicts between the googleMaps plugin and K2.

Please try (1) and (2) above and let me know the test result.

Regards,
