[Plugin: Events Manager] Permalink of events don't work when I click on it

Hello,
I have a problem with post events with this plugin.
When I click on a event that I post, it redirect me in the same page and not in the page of the event.
Ex: http://www.mariocatarozzo.it/eventi/
What is the problems?
Thanks for your plugin
