I am really confused. For all products that are drop shipped (no shipping required) I have changed the weight and volume to g and mm. THere is also zero for weight and dimensions for these products and in the config for shipping I have g,cm and mm,cm,m (changed it back)
Now when ordering an item that is shipped Australia Post and an item that is drop shipped, I am getting the error message "The cart items combined weight is too big for all the possible shipping methods"
Have no idea what to do about this.
