Wordpress LScache Plugin: Custom WooCommerce notices not shown on Safari/Chrome
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, writing this post I am referring to a previously opened request: https://wordpress.org/support/topic/custom-woocommerce-notices-not-shown-on-safari-with-quic-cloud-cdn/ Now we are facing the problem WITHOUT the CDN. In the dev env the notifications appear! The only difference between dev and prod environment was the object cache: in dev the feature was disabled. I tried to enable it and the notifications continue to appear. The ESI feature is disabled. The problem persists on Safari desktop and mobile, and Chrome mobile. I though that the problem was related to the browser cache, but I if try to leave a review when I am logged in as customer, the notification appears. I just made two reports, one for each environment: Development: AHEVKGVK Production: XLMHPJVI Could someone point me in the right direction? Any suggestion? Thank you, Nicola. PS: considering that the add to cart notice is shown correctly, is it possible that the problem depends by the system used to store it? The add to cart action is made with a POST to the product page, instead the save comment is made with a POST to the wp-comment-post.php, that sends back a location header to redirect to the product page. what was the http response header when it should give the notice ? Hello qtwrk! The response header was initially the standard for the inserted comments: Expires: (now + 10min) Cache-Control: max-age=600, must-revalidate I tried to force them this way (same as nocache_headers WP function ): Expires => Wed, 11 Jan 1984 05:00:00 GMT Cache-Control: no-cache, must-revalidate, max-age=0 But nothing changed? please post the full response header including the http status code on the page it should give notice Hello qtwrk! I rolled back my code to have the standard response. When I leave a review (remember that we are on woocommerce product pages): -> POST to wp-comments-post.php Request headers: :authority: www.________.com :method: POST :path: /wp-comments-post.php

Thank you for the support! Nicola I don?t see anything wrong from LSCWP side for instance, all these pages are giving x-litespeed-cache-contorl: no-cache which means page is not cached by LSCWP if you disable LSCWP, I assume it works fine ? what if you just use the default setting from LSCWP ? ]
