My WooCommerce store is losing sales because the cart goes empty right in the middle of checkout. Customers add products without any trouble, but the moment they reach the checkout screen every line item disappears, leaving them with an empty order and no way to pay. I need someone who has untangled tricky WooCommerce payment flows before and can quickly pinpoint whether the culprit is a theme function, session/cookie mis-handling, AJAX conflict, caching layer, or a plugin hook firing at the wrong time. I’ll give you full staging and production access, error logs, and a list of the active plugins so you can reproduce the problem. Acceptance criteria: • Cart contents remain intact from cart page through order confirmation. • Checkout completes successfully with at least one real or sandbox payment. • You provide a short summary of the root cause and the exact code or settings you changed so I can track future regressions. If you’re comfortable diving into WooCommerce hooks, PHP debugging, and browser console/network tracing, let’s get this fixed and restore a smooth purchasing experience for my customers.
