I did get it working again last night and then someone processed an order this morning and it didn’t work. * Do you know if there are any known issues with WP Super Cache or Minify type systems? I’ve disabled both in the meantime since those were the only things I thought could have been causing problems. * Plugin Author [fullworks](https://wordpress.org/support/users/fullworks/) * (@fullworks) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948124) * It shouldn’t impact it, but maybe – to be safe set youdomain-dot-com/?qpp_ipn to be not cached and see * Thread Starter [dangarion](https://wordpress.org/support/users/dangarion/) * (@dangarion) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948129) * I will let it run without any of them for a bit to see if things stay working… We don’t process a lot of orders since we are a non-profit disc golf club. I really appreciate your time responding to me. * Plugin Author [fullworks](https://wordpress.org/support/users/fullworks/) * (@fullworks) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948138) * Let us know. If you don’t really need a cache program ( and many sites don’t ) it does remove complexity. * Plugin Author [fullworks](https://wordpress.org/support/users/fullworks/) * (@fullworks) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948149) * By the way IPN keeps trying if it doesn’t get through for about 4 days. So if it is an issue with cache you will find that eventually that payment gets marked complete. * Thread Starter [dangarion](https://wordpress.org/support/users/dangarion/) * (@dangarion) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948161) * Arg… I got the sandbox to work and I turned it back on, processed a real payment and didn’t work again… I’ll check the log later, not really sure what I’m looking for as it seems to want to work and then decides it doesn’t when I turn it on.:/ * Plugin Author [fullworks](https://wordpress.org/support/users/fullworks/) * (@fullworks) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948249) * I assume you have double checked the IPN url in your production paypal notification settings for typos * Thread Starter [dangarion](https://wordpress.org/support/users/dangarion/) * (@dangarion) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12948293) * It would be hard pressed to be wrong since I copy and pasted it. 🤣. But I will double check. * Thread Starter [dangarion](https://wordpress.org/support/users/dangarion/) * (@dangarion) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12967162) * I think the issue was with Paypal. The delays have seemed to go away. * One more thing, I paid the annual upgrade fee… How do I indicate I have that within the plug-in? * Plugin Author [fullworks](https://wordpress.org/support/users/fullworks/) * (@fullworks) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12967270) * Hi, * Unfortunately WordPress dot org rules don’t allow me to support premium / paid questions on this forum. * Please contact me directly on support at fullworks dot net with details of your question. * Plugin Author [fullworks](https://wordpress.org/support/users/fullworks/) * (@fullworks) * [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12994639) * Premium query resolved offline Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘IPN Challenge’ is closed to new replies. * ![](https://ps.w.org/quick-paypal-payments/assets/icon-128x128.png?rev=3412386) * [Quick Paypal Payments](https://wordpress.org/plugins/quick-paypal-payments/) * [Frequently Asked Questions](https://wordpress.org/plugins/quick-paypal-payments/#faq) * [Support Threads](https://wordpress.org/support/plugin/quick-paypal-payments/) * [Active Topics](https://wordpress.org/support/plugin/quick-paypal-payments/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/quick-paypal-payments/unresolved/) * [Reviews](https://wordpress.org/support/plugin/quick-paypal-payments/reviews/) * 12 replies * 2 participants * Last reply from: [fullworks](https://wordpress.org/support/users/fullworks/) * Last activity: [5 years, 11 months ago](https://wordpress.org/support/topic/ipn-challenge/#post-12994639) * Status: resolved
