URGENT! ERRORS!

Hehe. Not sure what I'm testing against (new or old), but the error I see when I click the blue login-button is:
The Facebook Connect cross-domain receiver URL (<!-- m --><a class="postlink" href="www.jasonsfitkitchen.com/?fbc_channel=1#...%22%3A%220.919%22%7D">www.jasonsfitkitchen.com/?fbc_ch ... .919%22%7D) must have the application's Connect URL (jasonsfitkitchen.com/) as a prefix. You can configure the Connect URL in the Application Settings Editor.

That's stating that the Connect URL is set for the non-www version of your site. In the Facebook application overview, it should say something like:
Canvas Callback URL
<!-- m --><a class="postlink" href="www.jasonsfitkitchen.com/">www.jasonsfitkitchen.com/
Connect URL
<!-- m --><a class="postlink" href="www.jasonsfitkitchen.com/">www.jasonsfitkitchen.com/
Base Domain
- Since you're probably not using subdomains, try leaving this blank for now. Shouldn't matter either way though.

Verify that, and hopefully something will stand out.
