When google maps are not loading, check the following:
If you are on half map – make sure header of the page is google maps.
Or set just for the page you create, if it’s with the Properties List Half Map template
Or if you use SSL – enable SSL for google maps from theme options – Google Maps settings: http://help.wpresidence.net/article/how-to-setup-wordpress-and-theme-to-use-ssl/
If it’s not any of the above, disable all plugins (perhaps it is a plugin conflict).
If neither of these scenarios work please open a ticket in our private support – http://support.wpestate.org/login/ with the url in question and wp-admin access to assist further.
