Is the rest of your site functioning fine on the new permalinks?
I’m not sure switching permalinks should mess up the feed… but, have you made a new post since switching permalinks? If not, try that – it causes your feed to rebuild (just a quick post – you can delete it after testing)
yes, I’ve made some new posts and the my twitterfeed and facebook redirect weren’t working, so I decided to check my rss feed and it was the cause of the twitter and facebook redirect not working though.
Yes, it is working ok the rest of the site and the feed used to work before this permalink’s change.
