Wordpress LScache Plugin: Paypal ? IPN ? Nonce
Last Updated on: Wed, 15 Apr 2026 00:00:02 We seem to be having issues with Nonce and woocommerce paypal standard plugin, i think at the point of IPN calls, from the error logs: 2020-12-21T09:43:59+00:00 CRITICAL Uncaught WooCommerce PayPalCommerce Button Exception RuntimeException: Could not validate nonce. in /wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-button/src/Endpoint/class-requestdata.php:50 Stack trace: Is this a matter of adding nonce names to the settings somewhere> currently we do not have ESI enabled on this site as we dont want to serve cached content to logged in users. Hi, If you did not cache the login user, I dont think how the nonce would be cached ? what is the response header you see ? Best regards, the error seems to be hidden to the user, so im not sure what the headers are, IPN from paypal is getting a 200 header, it just that the IPN message is not being written to the order i think its that that throws the error to the log. The site is also behind cloudflare, so could that combination be causing an issue? Hi, I dont know , if you didnt use Cloudflare to cache pages , then I think Cloudflare has nothing to do with this. Do you have method to reproduce it ? Best regards, Hi, Im going to mark this topic Resolved , due to lack of activity. If you still need help, please feel free to re-open it. When re-open it, please also change the topic status to not solved Best regards,
