Google map not showing map

I have an working Google map API, and when I create a new event the maps is ok, but when looking on the same event from a calender, instead of a map I get this:

Google Maps l?stes inte in korrekt p? sidan.
?ger du denna webbplats? OK

(Google maps wasnt read correctly on the page. Do you own this web page?

I have been in contact with Google, say say API is okm but does not been used correctly by this plugin

The page I need help with: [log in to see the link]
