RSS Plugin

I am having trouble with my RSS plugin, which was working. I have another blog that I have integrated with Feedburner, and I had the RSS plugin setup to feed the other blog entries into my new wordpress site.

Now when I set up the RSS feed plugin I don’t get anything when I try to view my web site, only a blank page. When I remove the RSS plugin my new site shows up.

What do I need to do so that my RSS feed works again.
