Feed Problems with Blog Migrated over from Moveable Type T to WordPress

Hello. I just migrated my blog over from Moveable Type to WordPress. Everything seems to be working fine except for being able to subscribe to my blog feed.

My blog is located at https://markrogersphotography.com/blog

1) If I try to subscribe via the entries RSS link in my Meta widget I get the following error

XML Parsing Error: xml declaration not at start of external entity
Location: https://markrogersphotography.com/blog/feed/
Line Number 2, Column 1:<?xml version=”1.0″ encoding=”UTF-8″?>

2) On my old MT blog I had a feedburner subscribe set up and that no longer works either. When I try to validate the current feed I get the following

The URL you entered does not appear to be a valid feed. We encountered the following problem: Error on line 2: The processing instruction target matching “[xX][mM][lL]” is not allowed.

How can I fix this?

Thanks
