Thread:Extension talk:Maps/googlemaps error message: Your browser is not compatible with Google Maps v3./reply

Same problem.
 * MediaWiki	1.25.1
 * Semantic MediaWiki	2.2
 * Maps	3.2.3
 * Semantic Maps	3.1.3

It started to give me this error after some days that it worked fine. It's about the need of a API key?

Thanx in advance.
