地理编码服务：超出了API的每日请求配额

Question

HTML

<div class="google-map">
    <div class="map" id="map" data-address="Gatterholzgasse 14, 1120 Wien"> 
</div>

JS

google.maps.event.addDomListener(window, 'load', initMap);

function initMap() {

    var geocoder = new google.maps.Geocoder();

    var $maps = $('.map');

    if($maps.length) {
        $maps.each(function() {
            var map = this;
            var $map = $(this);
            var address = $map.data('address');
            var latLng, gMap, pin;

            geocoder.geocode({ 'address' : address }, function(results, status) {
                if( status == google.maps.GeocoderStatus.OK ) {
                    latLng = new google.maps.LatLng(results[0].geometry.location.lat(), results[0].geometry.location.lng());
                } else {
                    console.log("Geocoding unsuccessful. Reason: " + status);

                    latLng = new google.maps.LatLng(48.1792339,16.3194208,17);
                }

                var styledMap = new google.maps.StyledMapType(mapStyle, { name: 'Styled Map' });

                gMap = new google.maps.Map(map, {
                    center: latLng,
                    zoom: 17,
                    disableDefaultUI: true,
                    scrollwheel: true
                });

                gMap.mapTypes.set('map_style', styledMap);
                gMap.setMapTypeId('map_style');

                pin = new google.maps.Marker({
                    position: latLng,
                    map: gMap,
                    icon: './img/google-map/map-pin.png',
                    title: 'Gatterholzgasse 14, 1120 Wien'
                });
            });
        });
    }
}

Geocoding Service: You have exceeded your daily request quota for this API.  For more information on usage limits and the Google Maps JavaScript API services please see: https://developers.google.com/maps/documentation/javascript/usage

我试图更改API密钥，但没有任何改变。

我读到每天的免费访问限制是25000个唯一身份访问者，但我绝对没有。

任何建议将不胜感激。预先感谢
