WordPress MU

Hi,

My WP-MU installation at http://microreviews.org The RSS and RSS2 feeds are throwing an error.
RSS 2 URL : http://microreviews.org/feed/
RSS url: http://microreviews.org/feed/rss/
The error says:
This page contains the following errors:

error on line 1 at column 1: Document is empty
Below is a rendering of the page up to the first error

Please suggest a solution.

It's probably a plugin interfering. Turn them off and see if that fixes it.

yes, got it. It was a setting in YARPP where the RSS was also trying to fetch related posts. I disabled that and the RSS started working. Thanks a lot.
