Since April 1st the Googlemap is not shown anymore. This is due to a change made by Google to their API. The report from Firefox:
Error: window.jstiming is undefined
Source File: http://maps.google.com/intl/en_ALL/mapfiles/152d/maps2.api/main.js Line: 1115
This item is also discussed at the Googlemap API discussion forum at http://groups.google.com/group/Google-Maps-API/browse_thread/thread/90ae60390464a416?hl=en. A quote from this discussion:
Change v2.x to v2 -- 2.x is intended for testing, not for live sites.
It is quite easy to change. In the file googlemap.php in modules/googlemap, change v=2.x to v=2 in line 306.
See http://code.google.com/p/gmaps-api-issues/issues/detail?id=1193 for the Googlemap API bug tracker.
Attached is a new version of the googlemap.php file, which should be placed in the modules/googlemap directory.
