Hi,
Can anyone please tell me why the install is not updating the wb database.
may not help much, but I'm using XAMPP 1.7.2 (PHP 5.3.0, mysql 5.1.37) and 2 Tables are installed in DB. Only issue I got was an undefined variable "$markericondefinitions" on line 171 in functions.php. So for testing I would recommend not defining markers at the beginning.
Btw. did you recognize the link symbol in google maps, right above the map? This is not exactly similar to gmap module but helps for fast and easy providing maps on a site.
regards
