RSS feed errors

I just upgraded to 2.7 and my RSS feeds are not working – therefor my feedburner feed is not working. Looking through the forums I noted comments about removing spaces on various files and turning off plugins to see if it resolved my feed issues. I also looked at info on the support pages for my theme Thesis. But I am not able to get them working. Any support would be greatly appreciated. My blog is https://www.bethknittle.net/WP_Blog/

Thanks
