RSS Feed

Good afternoon, 

I'm having some troubles properly displaying the rss feed
on my site. I've
installed PHP-Wrapper and installed the rss-template that
was suggested in the
manual (adapted to my site).

Using Firefox, some details show up. Using IE nothing shows
up at all. I've seen
some Campsite-sites with the same problem, but some others
do have it working
properly. Can anyone help me?

The url is http://www.nieuwsbedrijf.

Thanks in advance!
