The most common reasons for what Google map is not loading are:

In WpResidence theme half map layout can be used on:

On these pages, google map must be set as a global header or as a custom header.

For the Advanced search results page and Property list page can set google map as global header or as a custom header.

For Taxonomy, pages can be set up only global header from Theme Options > General > Header.

If it’s not any of the above, disable all extra plugins and keep only plugins that come with the theme(perhaps it is a plugin conflict).

If neither of these scenarios work please open a ticket in our private support – with the url in question and wp-admin access to assist further.
