Wordpress LScache Plugin: ESI Nonces problem with EDD
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, A recent ESI Nonce rules update GitHub PR #366 which added the following rules, made the edd-gateway nonce invalid when using PayPal Express gateway: edd- private edd_ private I had to comment those rules on my local esi.nonces.txt file to make the gateway correctly work again. Note that I opened a report on GitHub Issue #399 2 weeks ago, and the support told me that CloudFlare APO isnt compatible with LSCWP. After that I totally disabled CloudFlare APO, but the problem persists. Youll find my fully detailed reports and monologue on that GitHub issue, including an another problem with ESI Nonces introduced in LSCWP 4.4 update, which was then fixed in the 4.4.1 recent release. But were now back to the initial issue, described above. I decided to open a report here since it looks like its the best place for LSCWP plugin support. Here is my LiteSpeed Report Code: QDAADFSJ Thanks in advance for your help. Regards. Hi, please check the Slack message Best regards, Hello, After some discussions with the LiteSpeed tech team, we stumbled upon an ESI logic limitation which doesnt allow nonce creation + validation within the same page request with ESI enabled, which was the case in the EDD-Recurring addon. This kind of operation doesnt have any pratical sense, thus why the bug wasnt spotted before. The solution is to remove the nonce from the ESI nonces rules list. Ill contact EDD team to let know that this nonce verification can be removed in the code, as it is useless. If someone need it, here is the filter Im using to remove global EDD ESI nonces rules added within the LSCWP plugin: / LiteSpeed ESI: Remove global EDD nonces rules / add_filter(litespeed_esi_nonces, my_edd_esi_nonces, 20) function my_edd_esi_nonces($nonces) // check nonces if(empty($nonces)) return $nonces $modified = false // loop foreach($nonces as $i => $nonce) // bail early if not edd if(strpos($nonce, edd-) !== 0 && strpos($nonce, edd_) !== 0) continue // unset unset($nonces[$i]) $modified = true // reorder array if($modified) $nonces = array_values($nonces) // return return $nonces Expand Thanks for your help! Regards.
