Using Leaflet Maps Marker , blank page?

Hi Leaflet Maps Marker Team

I am looking in to your plugin so using the 30days trial version.

when i add the map shortcode to my page everything goes blank?

See page below:

I use another plugin now but not sure if i keep this one and would then change to yours if it worked?

Can you help me out?
