Hi there,
It looks like your custom domain whyfarm.org goes to a self-hosted WordPress.org blog. I see that on that blog, you have a page called Levi and Kevin that you deleted from your WordPress.com blog, whyfarmdotorg.wordpress.com. Although whyfarm.org appears mapped to your WordPress.com blog, it is actually mapping to the self-hosted WordPress.org blog.
So in order to make changes to the site you see at whyfarm.org, you'll have to log in to your WordPress.org site and modify it that way. Making changes to the WordPress.com blog won't have any effect on whyfarm.org.
I hope that helps!
