RSS Feed Button Returns Code

I am really happy with my theme, and aside from not being able to figure out how to change the header in the sidebar from Blogroll to Links, my biggest problem is the rss feed. The sunflower in the header should like to the rss subscription, but instead, it returns code that appears to contain what would be the actual feed text. I tried deactivating all of my plugins and I tried the basic WP theme, and in all cases, I get the same result. Any idea what I should try? Thanks!
