Posts Locator Function – Not working

Hello,

I can not get the “Posts Locator Function” gmw_update_post_location( $post_id, $address ); work with the Google Maps API Key. I followed your instruction https://docs.gravitygeolocation.com/article/134-how-to-create-browser-and-server-google-maps-api-keys to create 2 Keys, browser and server key.
It does not work/update.
When I use LeafLet it works fine. Even if I update with an Address string or an lat/lng array.

So it must be something with the google API. And, I cant even find your TESTING Tab for checking if the API works ??

I am Using the WPUF pro. And I use this funuction:

function update_GEOmyWP( $post_id ) {
	
// make sure post ID exists.
if ( ! $post_id ) {
	return;
}

// verify the updater function.
if ( ! function_exists( 'gmw_update_post_location' ) ) {
	return;
}
	
if ( isset( $_POST['aufnahmeort'] ) ) {
	
	list( $adresse, $lat, $lng ) = explode( '||', $_POST['aufnahmeort'] );
	
	$location = array( $lat, $lng );
	
	if ( $adresse ) {
		update_post_meta( $post_id, 'newADDRESS', $adresse );
	}
	if ( $lat ) {
		update_post_meta( $post_id, 'newLAT', $lat );
	}
	if ( $lng ) {
		update_post_meta( $post_id, 'newLONG', $lng );
	}

	gmw_update_post_location( $post_id, $location );

}
}
add_action( 'wpuf_add_post_after_insert', 'update_GEOmyWP' );
add_action( 'wpuf_edit_post_after_update', 'update_GEOmyWP' );

Please help ??
Cheers,
Denis
