Events not loading

Hi,

The plugin is very great, but the events not loading in calendar.

Json generated automaticaly by plugin in load calendar is: http://andifes.web2151.uni5.net/final/wp-admin/admin-ajax.php?action=WP_FullCalendar&type=events&month=7&year=2015&start=2015-07-26&end=2015-09-06&_=1440101705953

Calendar Demo result Json different: http://demo.wp-events-plugin.com/wp-admin/admin-ajax.php?action=WP_FullCalendar&type=event&month=7&year=2015&start=1440990000&end=1444532400&_=1440100918101

If I change url to: http://andifes.web2151.uni5.net/final/wp-admin/admin-ajax.php?action=WP_FullCalendar&type=events&month=7&year=2015&start=1440990000&end=1444532400&_=1440101705953

I have positive result. What my mistake in configurations of the plugin to generate the wrong url?
