Thread:Extension talk:Maps/Maps Extension not starting

Hello everyone,

I have tried to use the Maps Extension for later use by Semantic Maps and encountered the following error message:

Warning: include_once(__DIR__/includes/services/GoogleMaps3/GoogleMaps3.php) [function.include-once]: failed to open stream: No such file or directory in /var/www/vhosts/h1753510.stratoserver.net/httpdocs/wiki/extensions/Maps/Maps.php on line 229

Checking on the very first error message I can confirm the following:
 * GoogleMaps3.php is installed and within the specific directory
 * Validator extension is of latest type (just downloaded and installed as well)

I am at a loss what I can do. Do I have to configure it somehow, if yes where?

Looking forward to your help!
