Maps does not load

Can you try to add this code to the functions.php inside your active theme folder, and see if that fixes it? Replace ‘your browser key’ with the actual key.

add_filter( 'wpsl_gmap_api_params', 'custom_gmap_api_params' );

function custom_gmap_api_params( $api_params ) {

    $api_params = $api_params .'&key=your browser key';

    return $api_params;
}
