I am unable to change Locale options in Stores >> Configuration >> General tab Configurations. After saving the configurations it shows 'You saved the configuration.' but there is no change.
Flushed the cache, reindexed but still no change. Checked console but no error in console.
update 1 Disabled all third party extensions but it still didn't worked.
update 2 Can't save any general configuration in Default Config store view.
