WooCommerce checkout not working: most common causes & fixes

Problem

Customers can add products but the WooCommerce checkout spins forever, shows errors, or won’t place orders.

Solution

• Temporarily disable caching/minification and test checkout again (especially JS minifiers).
• Check payment gateway plugin logs and ensure webhook/callback URLs are correct.
• Look for theme or plugin conflicts (disable non-essential plugins and retest).
• Verify SSL and mixed-content issues; checkout must be fully HTTPS.

Quick checklist

• Disable cache/minify
• Review gateway logs
• Conflict test plugins
• Check HTTPS / mixed content
