    The url request for admin-
   ajax.php return a error 500 : [http://mainsite/subsite/wp-admin/admin-ajax.php?action=WP_FullCalendar&type=patient&post__in=708&post_type=patient&posts_per_page=-1&month=0&year=2016&start=2015-12-28&end=2016-02-08&_=1453829882873](http://mainsite/subsite/wp-admin/admin-ajax.php?action=WP_FullCalendar&type=patient&post__in=708&post_type=patient&posts_per_page=-1&month=0&year=2016&start=2015-12-28&end=2016-02-08&_=1453829882873)
 * I have tried this :
    WP Fullcalendar network activated WP Fullcalendar subsite
   activated And also trying to disable Domain Maping extension option : “Redirect
   administration pages to site’s original domain (remote login disabled if this
   redirect is disabled)”
 * This is a very big problem, could you help me ?
    Thanks
