David Gewirtz on "Seamless Donations PayPal IPN Failure"

I have no idea what this line is from. Not Seamless Donations:

http://www.missingpetpartnership.org/?wpbdpx=payments&action=notify&payment_
id=38

This URL responds correctly:

http://www.missingpetpartnership.org/wp-content/plugins/seamless-donations/d
gx-donate-paypalstd-ipn.php

I'd take a look into whatever other plugin you're using to talk to PayPal.
