Blogspot blogroll could not detect wordpress feed

Hi,

My blog is at https://www.iamthewitch.com and my feeds are at https://feeds.feedburner.com/iamthewitch. My friend who’s using blogspot is trying to add my blog to the blogroll, but every time she tries, there’s a message “Could not detect a feed for this URL” error message. How do I modify my template/feeds so that my blog can appear on her blogroll with my recent updates?

Thank you.
