[SOLVED] Is the built-in Wordpress feed available with Atahualpa?

I have a client who does not want to have to sign up for Feedburner, and I read on the Wordpress site that it comes built in with feeds. Unfortunately I can not get the links it mentions to work.

There are times when you want to tell someone your site's feed address or URL, or you need it to submit it to search engines and directories, many of which now accept feed URL submissions. There are four possible URLs for each of your feeds. Any of these will work.

http://example.com/?feed=rss
http://example.com/?feed=rss2
http://example.com/?feed=rdf
http://example.com/?feed=atom

I get an error that says "Feeds are not available for this site.".

Is there something in the theme stopping the built in feed from working, or something else I should be doing? The site is locked down right now, until we launch, so I can not share a link to it directly. If anyone needs further information, just ask and I shall provide. The link on Wordpress.org I was looking at is here: http://codex.wordpress.org/WordPress_Feeds. It mentions about adding in the feed, but I am not sure what PHP file I should be doing that.

Thanks in advance for pointing me in the right direction!
