RSS Feed Disabled

I recently upgraded my WordPress to the most recent (something I keep up with on a regular basis). However to my disappointment I realized that my RSS feeds haven’t worked since! I’ve looked around the support forums trying to discover the cause but so far I haven’t been able to find out what the reason is.

I’ve disabled all my plug-ins to ensure it wasn’t one of those that was causing it, and I’ve been going through suggested files and removing any blank lines before <? sections. Still no results however.

Anyone’s suggestions or ideas are much appreciated!
