Open Pages in WordPress and identify the intended Cart, Checkout and My Account pages. Check for duplicates created by earlier imports or setup attempts. Record the current assignments before changing anything, especially on a live store with custom checkout links.

1. Edit the Cart page and confirm it contains the Cart block or the supported classic cart implementation.
2. Edit the Checkout page and confirm it contains the Checkout block or the supported classic checkout implementation.
3. Open WooCommerce > Settings > Advanced and assign the intended published pages.
4. Review the My Account and terms page assignments where applicable.
5. Save, then follow the store's own cart-to-checkout links from a logged-out session.
6. Check that the assigned pages are excluded from inappropriate full-page caching.

If the store deliberately uses the supported classic flow, edit each assigned page and place its matching shortcode in a WordPress Shortcode block. Use these on separate pages:

Use one intended implementation on each page. Do not add the classic shortcode below an existing Cart or Checkout block as a general repair. Save the pages, verify their assignments under WooCommerce Settings, and test with a product in the cart. If the store uses the modern blocks successfully, keep those blocks unless a reviewed compatibility requirement calls for a change.

Use separate pages for the normal WooCommerce workflow. Combining roles or placing multiple checkout implementations on one page can create confusing routing and state. A specialised one-page-checkout extension needs its own documented setup and compatibility checks.

WooCommerce provides system tools that can recreate missing default pages, but review the existing content and assignments first. Recreating pages repeatedly can produce duplicates and does not necessarily restore custom design or URLs. After recovery, update navigation and redirects for any changed public addresses.

Check whether the cart actually retains the product, whether cookies are accepted and whether caching or redirects discard the session. An incorrect page assignment is only one possible cause. Test a simple product with a clean browser session before changing several settings at once.

Add an item, change quantity, proceed to checkout and submit a sandbox order on staging. Verify the order-received page and account links. Check mobile navigation and translated page variants if used. Preserve the final page IDs and URLs in the store's operations record so future design work does not accidentally replace a functional checkout with an ordinary content page.
