After updating the theme to version 2.5.2, if you're using the Google Maps page builder element in one of your pages (e.g. Contact page) you'll notice the map will no longer display but show the shortcode instead:
Due to changes in Google Maps resulting into console errors, the Google Maps page builder element was removed and the native WPBakery Page Builder maps should be used instead.
So to get past this issue, you need to remove the old map and simply insert the Google Maps element again. That's all.
