Hi, I've seen this question raised before here (https://www.paypal-community.com/t5/About-Payments/IPN-with-notify-url-variable-works-in-Sandbox-but-not-on-live/m-p/658098#M12975) but I haven't seen an answer other than open a ticket? I created a button using payapl's online button creator and supplied the notify_url in the button and paypal_ipn is switched on in my account. I run the ipn test in payapl developer and it returns successfully, I run it from my live site (using the same notify_url) and I get a 500 error in the ipn history. Is there any information on troubleshooting the ipn process? I've checked the logs on the live server and nothing jumps out as a problem. Any adive would be great, I need this sorted. Thanks.
