Debug Mode
To enable Debug Mode, go to Woocommerce > Settings > Shipping > FedEx and mark the checkbox next to Enable debug mode option. As a result, you will see two custom messages in checkout/cart pages: FedEx: API request and FedEx: API response.
Enabling the Debug Mode will let you identify and analyse the problems with FedEx services price calculation. After turning it on, all the requests, responses and the error messages coming back from the FedEx API will be displayed in the cart and on the order summary page. All the notices and data generated by enabling the Debug Mode will be visible only for the Site Administrators and Shop Managers. Your customers, no matter if they are guests, or they are logged in, won’t see any unnecessary info in the shop’s frontend.
