RSS Header Only (No post info)?

For 2 sites that I have recently updated, all of the feeds are for some reason only showing the feed header info:

https://www.faithability.org/religiondisability/wp-rss2.php
https://www.faithability.org/religiondisability/wp-rss.php
https://www.faithability.org/religiondisability/wp-feed.php
https://www.faithability.org/religiondisability/wp-rdf.php
and
https://www.faithability.org/religiondisability/wp-atom.php

The feed header info appears to be correct, but none of the individual post information shows up since I have upgraded to 2.0. Before that, the feeds worked fine… I’m still figuring my way around WP and haven’t been able to figure out what is common to all of these that isn’t working- any ideas?

I am using a theme that I used in 1.5, is there something in the new themes that could be causing it?

Thanks-
