Adam's dashboard

I can't set up Blog trips from Dopplr to my personal weblog.

I am using Blogger, and I get this error:

Couldn't add that weblog, your blog server reported this problem: unexpected response Content-Type: "text/html". should be one of: ["application/atomsvc+xml"]

I have modified the 'advanced settings' to use this Endpoint: http://www.blogger.com/atom/

What else should I be doing?
