The Map not Function

I used the template core minimalist photography portfolio https://themeforest.net/item/core-minimalist-photography-portfolio/240185 and wordpress version 3.3.1.
The map once you load the gpx or kml file does not work. See here https://www.roundabike.it/zona_naviglio/. I contacted the owner of the theme and told me this: There are javascript conflict between theme’s script and plugin’s script.

Really sorry, I can not support on all 3rd party plugins issue. Please try to read its documentation or contact plugin author.
