Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Eleven theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.
So step 1 provided some insight – an unformatted version of the feed shows when all plugins are active EXCEPT my “advanced permalinks” plugin… when this plugin is deactivated, this is what shows:
This XML file does not appear to have any style information associated with it. The document tree is shown below.

When I use feed validator (while the “advanced permalinks” plugin is deactivated), I get the following error message, which seems to be related to the “advanced permalinks” feature where i renamed old post URLS to be “pretty permalinks”:
Sorry
This feed does not validate.
line 172, column 61: guid values must not be duplicated within a feed: http://theworkoutgirl.com/?p=1611 [help]
<guid isPermaLink=”false”>http://theworkoutgirl.com/?p=1611</guid>
How do I resolve this issue? Thanks for your help!

That sounds like a normal RSS feed.
Your feed works fine. How you redirect your old permalinks to the new one?
