Hi LiteSpeed Team,

I am opening this ticket regarding an issue we are experiencing on our site (collectionprivee-paris.com) following the recent WooCommerce update.

Issue Description

During checkout, some customers experience continuous loading/spinning wheels when trying to place an order. Eventually, the session times out, displaying a “Session Expired” message. As a result, several customers re-submit their payment, causing duplicate orders and charges.

Isolation & Testing

• When we completely disable all LiteSpeed Cache features, the issue disappears: checkout flows smoothly, sessions do not expire, and no duplicate orders occur.
• Enabling LiteSpeed Cache (specifically page caching / JS optimization features) reproduces the continuous spinning and session timeouts on the checkout page.

Environment Details

• Site URL: https://collectionprivee-paris.com/
• WooCommerce Version: 11.2.1
• LiteSpeed Cache Plugin Version: 7.9.1
• WordPress Version: 7.1.3

Current Exclusions & Settings Overview

We have already applied strict exclusions to prevent LiteSpeed from interfering with the checkout flow. Here is a summary of our current configuration:

• Excluded Cache URIs (cache-exc): /cart/, /checkout/, /my-account/, /step/, order-received, order-pay, /wc-api/, /wc-auth/, /wp-json/, /wp-admin/admin-ajax.php, /wp-cron.php
• Excluded Cookies (cache-exc_cookies): woocommerce_cart_hash, woocommerce_items_in_cart, wp_woocommerce_session_, wordpress_logged_in_
• Excluded Query Strings (cache-exc_qs): add-to-cart, wc-ajax
• JS Defer / Minification / Exclusions (optm-js_exc & optm-js_defer_exc): jquery, jquery-migrate, woocommerce, checkout, stripe, paypal,express-checkout, cartflowsetc.
• Object Cache (object): Enabled (Memcached/Redis via port 11211 with wc_session_id in non-persistent groups).

Could you please advise on the recommended cache/optimization exclusions or configuration settings to prevent LiteSpeed from interfering with WooCommerce checkout sessions and AJAX payment calls?

Thank you for your support!
