Error processing checkout. Please try again

Overview

Generic checkout error after submission.

Root Cause

• Validation failed (missing required fields, terms not accepted).
• Gateway/API/timeout error, or nonce/session expired.

Impact

• Order not created or payment not captured.

How to Fix the Issue

1. Fill all required fields and accept Terms & Conditions.
2. Refresh the page/session, then try again.
3. Check gateway logs and API credentials; fix any errors/timeouts.
4. Disable conflicts temporarily (custom code, checkout field editors) and retest.

Additional Notes

• Enabling WooCommerce logging helps trace the failure.
