 * Sounds like one (or more) of your products has an invalid tax class.
 * To diagnose the problem:
    1. First clear the local product data by going to the Support tab in the POS. Then
       refresh the POS to make sure you have fresh data from WooCommerce.
    2. Find a product that reproduces the error.
    3. Go to that product in the WooCommerce admin and check the tax_class setting.
       You may need to update and save the product.
    4. If you do change any products remember to clear the local data to make sure 
       you have the updated version in the POS.
