IPN listener stopped working

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...

This happened to me last month. I may have solved it, but I'm not sure yet, even though it has worked in testing. Did you figure it out?
