To clear cache in a WordPress WooCommerce site, start with your caching plugin: open its settings and click Purge/Clear All Cache, then clear CSS/JS and preload if available. Next, purge any server cache from your host panel (LiteSpeed, Nginx, Varnish) and clear Redis/Memcached object cache if enabled. If you use a CDN like Cloudflare, purge cache (or purge only /shop/, /product/, /category/). In WooCommerce, go to WooCommerce → Status → Tools and clear transients and product lookup tables if needed. Finally, hard refresh your browser and test the cart/checkout. Also, clear your browser cache on mobile, and retest after logging out.
