Same Problem

Using vB 3.6.4 the Installation works without Problems but after Installing the URL /vbgooglemapme.php only shows an empty page without anything :/
I created an account for the API and got my API code.
I already set the permissons for the markers.php
All Usergroups have their defined color
But it doesn't work anyway.
Neither IE nor Firefox are telling me faults.... There's just an empty page *damned*
Any idea what's wrong?
