WordPress RSS Hijack?

I received an email from Feedblitz that my Feed URL has changed. Upon checking, I noticed the following:

Accessing http://feeds2.feedburner.com/RaymondccBlog brings me to http://feeds2.feedburner.com/j?GLEKk5qHf3W556ucwTFm3i9ibG9nL2ZlZWQ= which is not my feed.

If you access http://www.raymond.cc/blog/feed/ , it auto redirects to feedburner and then to the hijacker page.

Try accessing http://www.raymond.cc/blog/feed/rss/ and it’s working.

Has anyone seen such problem before? Theoretically, Feedburner gets the feed from my blog and since Feedburner is redirecting, so it could be a problem with my WordPress.
