Hi
Several years ago I created an IPN listener (using PHP) based on a code sample that was provided by PayPal's Integration Guide(s).
It worked beautifully for years - and then stopped!
PayPal support say that the IPN is working and that my listener is correctly verifying the responses etc but it won't do what it used to do.
I have a feeling that PayPal have changed things and left my code behind. I have looked on github but the example code they are giving does not make sense to me.
Please can someone help. I have copied my listener code below. Can someone please just tell me what is wrong and what I need to do. This is driving me up the wall!
Thank you very much...
