Please help!!

No one will help me with this.. I have tried posting under how-to, but I thought maybe I’m not supposed to post a page link in there, but that is the only way to help me. I did some modification to a wp theme only to add a few things like adsense, etc. Now I can’t get my Rss feeds to work… there is something like 42 errors. Could someone take a look and see if you can figure it out? I just can’t fix this. I have been trying literally all day, no one here has even answered my posts. If there is something wrong with the way I’m asking or something, please let me know so I can get someone to help me!!!!
