Disable state/province option in the Magento

Sometime your Magento site doesn’t need the region/state for customer address and you don’t know how to turn it off without touching in many places in the complex Magento source code. Please try to run following SQL statements to try

1 2	update core_config_data set `value`=0 where path = 'general/region/display_all'; update core_config_data set `value`='' where path = 'general/region/state_required';
