First, thanks for your work on this.
This is a great plugin.
I would like to upgrade from 7.0.31 with our upgrade to WP 3.8.
I have tried 8.0.2 and 9.0.17.
Both result in endless map "loading".
Production site running 7.0.31: http://papercrafterscorner.com/papercraft-stores-map/
Staging site running 8.0.2: http://pccorner.staging.wpengine.com/papercraft-stores-map/
WP: staging: 3.8
