Magento 2.1.4 : Disabled flat rate via store > configuration > sales > shipping method like this:
I have already deleted the cache, upgrade, static content deploy but it keeps showing the flat rate at checkout:
i checked the core config data, turns out there was flat rate that was still active:
but when i set the active value to zero, and cleared cache and etc, when i go to /checkout and fill address and post code , its not triggered to refresh the shipping method, so it said there is no shipping method available
