Spent most of the day debugging our code that communicates with PayPal for the new subscription feature. It suddenly decided not to work, after working fine for a long time; I’m pretty sure PayPal changed something about their IPN (Instant Payment Notification) system, and it stopped accepting post-backs to the non-HTTPS version of their URL.

Wasn’t easy to track down, but the bad code was buried in a PHP class I’d been using for years. Rather than try to edit that, I just wrote a new IPN listener from scratch. So now if things go wrong, I have only myself to blame.

Was the old class a third-party library you’d picked up along the way?
