PayPal orders suddenly stopped showing in store

Using PayPal IPN
Zen Cart version 1.3.7a

Orders are going through PayPal fine, but are not showing up in Zen Cart. This started happening on or around Feb 14.

My log file - Log file

I ran ipncheck.php and it ran fine.
I ran curltest.php and errors came up on parameters ?paypal=1 and &proxy=1. Results are in things to check

It is working again, at least for now. The IPN settings in PayPal were incorrect. It is a mystery to me how it was working for 3+ years with the incorrect settings and suddenly stopped. It appears that the settings may have been very old settings and PayPal changed something recently so they no longer work.

Hey,

Same thing going on here and it happened around the 10th. I talked with paypal and they are going to a new and improved version/update to their servers....I have yet to get it to work again. Mine is still taking the payment, but not bring the information back so that I know what that customer ordered.

Have lost a few sales from this fiasco and finally had to drop paypal as an option for checkout. We run our own merchant account here at the shop...so its plugging in all the info in the mornings that's a pain, but a least no more lost orders except for the people that have a PayPal account and no CC.
