If your map does not get loaded and you see an error like the one above (error details are only visible for admins), this can have the following reasons:
- WordPress AJAX endpoint cannot be accessed
This is the most likely reason and can be either caused by security plugins or c onfiguration in wp-config.php or .htaccess (in root or /wp-admin) which prevent calls to the general WordPress AJAX endpoint at /wp-admin/admin-ajax.php
Accessing that endpoint is needed for maps to load properly, so if this is the case on your site, please remove those restrictions.
