[Plugin: Donate Plus] Donor Wall Help?

I’m having the same problem that I’ve seen others post, but unfortunately those threads has been closed without a clear resolution for them.

I have posted the [donorwall] and [donatetotal] shortcodes on my page http://www.laundrybasketsfulloflove.org/donors but the data does not show up.

My IPN URL is set up in PayPal. I’ve made a couple of manual code changes to the donate-plus.php file that another user suggested, but still no change.
