If you want to reset and restore the default shipping methods in WooCommerce after modifying or disabling them, follow these steps

Step 1: Remove Custom Code

• Go to your theme’s functions.php file or your custom plugin.
• Remove any code that filters or disables the WooCommerce shipping methods (including the previous custom shipping code).

Step 2: Reset Shipping Zones

1. Navigate to WooCommerce > Settings > Shipping.
2. Delete any custom shipping zones you may have added.
3. Recreate new shipping zones and assign shipping methods such as:
   • Flat Rate
   • Free Shipping
   • Local Pickup

Step 3: Clear WooCommerce Cache

1. Go to WooCommerce > Status > Tools.
2. Clear these:
   • Clear WooCommerce Transients
   • Clear Expired Transients
   • Regenerate Shipping Zone Cache

Step 4: Test Default Shipping

• Add a product to the cart.
• Check the cart and checkout pages to ensure default shipping methods are back.

Optional: Debugging

If the default shipping methods are not appearing, enable debugging:

add_action('woocommerce_package_rates', function ($available_shipping_methods) {
    error_log(print_r($available_shipping_methods, true));
    return $available_shipping_methods;
});

Check the wp-content/debug.log file for any issues.
