RSS Error

I use feedburner for my RSS feed and on my page where I have it set to show recent posts from the feed I get this message:

RSS Error: XML error: syntax error at line 3, column 57

In feedburner – I am getting this message:

The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 1: White spaces are required between publicId and systemId.

I recently changed by permalinks from the standard ?=187 kind of format to where it shows the post’s name in the URL. I’m guessing that has something to do with it.

Anybody have any idea what these error messages mean and how to fix it?

Thanks!
