I set up the free Method into UPS Ground and save it. After the page reloaded and the system says that "The configuration has been saved". I'd expect that my changes are saved and ready to be used but the Free Method option is turned back to None.
I also set up the Free Shipping but the still I cannot save the UPS Free Method into Ups Ground it was always set as None.
PS. There is no generated shipping_ups.log on var/log even the Debug option in UPS is On.
that's why I didn't know what are the errors.
Can you give please give me an idea to solved this problem? Advance Thank you.
My Magento version is 1.9.4.1
