I turned on the spider friendly URLs and the RSS feed in the categories are not working. The RSS for the whole site is working and can be seen here Fresh Dames
but for a category it doesn't form a proper xml file. You can see it here - Celebrity Pictures
I toggled back and forth with the SE friendly URLs and when the SE friendly URLs are turned on it doesn't work but when the SE friendly URLs are turned off it works. I think the issue is a malformed URL when it's in SE friendly URL mode.
Actually I just clicked on one of the URLs in the RSS feed that works and noticed that the URL is not the SE friendly version. So basically the RSS feed doesn't maintain the SE friendly URLs at all.
