Problem with Events Calendar Page after plugin update (2.5.2)

Hi,
i have a problem with the Events Calendar Page after plugin update (2.5.2).
The page is this: http://www.goldenbookhotels.com/offerte-ed-eventi/calendario/

If you visit the page, you see a blank page, but there are 3 events from 1st June to 31 December.

If you clickon the little arrows to go to previous months, the Events appear.
If you try to choose e date after June, the calendar doesn’t run and come back on June.

Can you help me please?

Thank you! bye
