Solution: Ensure you are using a payment gateway that’s compatible with your WooCommerce version. Always keep WooCommerce and its plugins up to date.

3. Expiry Date Error

Problem: Customers receive an error message about the card’s expiry date, even if it’s correct.

Solution: Advise customers to check for typos and ensure their card is not expired. If the issue persists, contact your payment gateway provider to verify your gateway’s configuration.
