I've been using Amember in conjunction with PayPal and IDevAffiliate for a few months now. I've been using it for one-time payments of a digital product. I've got it working for the most part, but have never quite gotten it to run smoothly. Today I received and email from PayPal stating: "Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:" and then referencing my Amember IPN URL: http://mysite.com/amember/plugins/payment/paypal_r/ipnr.php Before this occurred I noticed that my Amember database was quite large. Then I realized that most of the mass was from the error logs. These all referenced issues with the PayPal transactions. The odd thing is that they seem to eventually go through and I haven't heard of any complaints of not being re-directed to the download page, but when sandbox testing it did sometimes seem to take a few page refreshes after the purchase for the member page to reflect the payment and provide the link for the download. Also, even though I've setup IDevAffiliate to connect with Amember and they do seem to work together, only about 1 in 5 Order #'s show up in the affiliate sales so it's often hard to matchup what affiliate sale goes with what Amember transaction (it would be one thing if they never went through, but it's just odd that sometimes they do and sometimes they don't). I have this link in the Amember Resent Postback option box (mysite.com is obviously not my domain): http://mysite.com/amember/plugins/payment/paypal_r/ipn.php but I actually have an ejunkie IPN URL in the IPN section of my PayPal account (because I also use ejunkie for some other products. So with all this info, am I doing something wrong or is there something I can adjust to fix the IPN issue? At this point PayPal is saying that: "If this problem continues, IPNs may be disabled for your account." So I need to get it resolved ASAP. Thanks for any assistance! Eric
