Not able to view Calendar

I’m not able to view calendar when I preview it. I’ve entered two events and when I click to see what it looks like in the calendar view it takes me to this page: http://caymanheartfund.com/events/

I’m using this WP template: http://themeforest.net/item/advocator-professional-nonprofit-organizations/7006346

Have no clue what to do from here.
