Can't get comments to work

Hi there, I have created an app and connected it to the site correctly (no errors) but comments do not show up and aren’t imported. Tried for 3 days now! I only get the comments box but not the comments from Facebook. Help!!

I get these errors messages:

Here is an url (with comments in Facebook)

Facebook Url with the comments:
