Anyone else have this problem?

Only my RSS and Comments feeds will display in WordPress 2.7. The others -- RSS2, Atom, Categories and Tags -- will not.

These will display:
RSS: dwarfurl(dot)com/607d8
Comments (individual post): dwarfurl(dot)com/5f71c

Most others will not display. Here's a category feed, for example:
dwarfurl(dot)com/f52b0

RSS 2 will not display: dwarfurl(dot)com/d3439

I'd appreciate any suggestions.

Thanks!
