Hi
You need to copy the code from Google map plugin code container and use this code in map
Open file "/html/layouts/joomla/contact/masthead.php" in template "ja_diner"
Find
{jamap}
Replace it with map code
Also the current API is not valid, check the Google map account , as this API key is not for this site domain.
If API is not valid in Google map plugin, it will not work.
