Aaron,
Facebook will use the SSL version of your site whenever a user is logged into Facebook. There is information that they transfer to your website through the iFrame they use about the current user, and so therefore, Facebook encrypts that information. When a user is not logged in, they may or may not load the site over SSL (it varies on a few factors). That is why they ask for both a Canvas URL and a Secure Canvas URL; they want the ability to choose the right one for the situation.
With that said, when I go to the apps page you mention above, I get an error message (in Chrome) that states:
Error 501 (net::ERR_INSECURE_RESPONSE): Unknown error.
If I go to your SSL site directly
yioceanside.org/, I get a security warning that the SSL certificate is not trusted by a root authority. I'm not sure where you got your SSL certificate, but you will need one that has been validated by a root authority (Comodo, Verisign, etc). You cannot use a self-signed certificate, if that's what you're trying.
I think once you get the SSL issue worked out, you should be up and running. If this doesn't help though, just let us know!
Thanks,
Alex
