It’s currently happening on my WordPress blogs as well. No feeds showing. I’m running off Dreamhost.
You’ll need to go into your sidebar template or into your links list (depending on where you defined the home page link) and remove all text for the link definition of the URI after http://www.cupesudbury.org/
This seems to be over-riding your is_home() tag on your page template for displaying the page title.
Your error reads:
Warning: Cannot modify header information – headers already sent by (output started at /home/technolo/public_html/wp-content/plugins/adsense.php:115) in /home/technolo/public_html/wp-rss2.php on line 10
Try disabling adsense and try looking again.
Thanks for the update! It was easy to install, although I had only hacked one file so it wasn’t difficult to work with the changes.
