I updated my theme (heartfelt by Rescue themes, version 2.0) as well, but no improvement, the map still doesn’t show. Any ideas? it’s not possible for me to test on every single theme: I usually test on default WP themes each new release. What I can guarantee the plugin uses all best practices for plugin development so should be compatible with all compatible themes for WP. As always, having a link to check and all details about steps to create and make the map live are more then welcome :-) I’ve noticed there is another piece of shortcode not showing at the bottom of the page :Source.
