Feed Not Available

After adding a .htaccess file to my server, the feed for my WordPress installation is not working properly. If I browse to the feed URL, I get a basic “this page cannot be displayed” error.

Specifically http://www.suzieanded.com/blog/?feed=rss2 redirects to http://www.suzieanded.com/blog/feed, which is “not found.”

I suspect that there’s a simple solution to this, but I don’t know what it is.

Thanks.
