Feed not showing

Hi

What ever I do I can’t manage to get the feed over here
https://iqdemos.net/kibuz/
I try to get feed of this page: https://www.facebook.com/pages/%D7%A7%D7%99%D7%91%D7%95%D7%A5-%D7%A6%D7%91%D7%A2%D7%95%D7%9F/153052881519276

1) I created an app
2) I put 153052881519276 as id but it doesn’t show

what do I do wrong?

thanks!
