Null exception when loading remote ical file

Scheduler Javascript
#1

Hi,

I have configured the scheduler to load a remote ical file (a calendar from AirBnb). When I am testing my scheduler locally, the calendar is correctly loaded and displayed.
However, when I am uploading my scheduler to my web server, and try to load the calendar, the dhmx scheduler returns me a null exception “TypeError: b is null” at dhtmlxscheduler.js, line 190. It looks like that the dtmlXMLLoaderObject.xmlDoc respnse is an empty string.
You can access and test the calendar at paponie.fr/calendar/calendar-hp.html.
What am I doing wrong ?

Thanks

scheduler.load("https://www.airbnb.com/....","ical");
[/code]scheduler.load uses AJAX and browser won't allow cross-domain ajax requests.
you can receive data some other way and then add it to calendar with scheduler.parse[code]
scheduler.parse(data, "ical");
