Reset RSS

Hello, so even before I upgraded to 3.3, my RSS feed was having problems. My feed looks like this: http://www.dropofcolour.com/feed/
I tried looking at the codes, but I can’t seem to find the problem. So is there any way or files that I can just reupload to override the current one to fix the problem?

Which files for RSS would I have to rewrite?

Thanks in advance.
