angelo, regarding your link, the first event that is shown to me is on the 7th January.
I have exactly the same problem! Future events are missing!
I get the same problem even on http://demo.wp-events-plugin.com/calendar/
Here is the screenshot: http://www.redsnowcat.ru/wp-content/uploads/2014/02/wp-fullcalendar-no-events.jpg
I use Firefox browser. It shows that AJAX returns all valid events but somehow most of them are not shown.
