Integrating Elgg RSS feed into Google Sites

Hi there,

I tried adding Elgg RSS feeds to Google Reader. No problem there, everything works just fine. But if I try to add an RSS feed to a Google Site, things don't work. I add the RSS reader widget to a Google Sites page, then add the RSS feed to the reader, but nothing happens. I tried a few RSS reader widgets, none work.

This is an RSS feed for testing purposes:

If you throw it into an RSS validator, it gives minor issues, but Google Reader is able to read it anyway. Anyone any ideas why it doesn't work on a Google Site?
