RSS feed loading homepage?!

hey all. my rss feed has worked perfectly until only a few hours ago! suddenly when i go to my feed (http://prettymuchamazing.com/feed) it loads my homepage as my feed. Note that I do use a feedburner plug-in that is supposed to redirect my “/feed” to http://feeds.feedburner.com/prettymuchamazing . I’ve been using this plug-in for 6 months already. Nothing like this has ever happened.

any help is MUCH appreciated! thanks
