I am using two store for my website one is for India and other for global(other country).
for Global is used paypal payment method. in global store currency is USD, India store currency is INR, Default config currency is USD. When i going to place order using paypal payment method in global store. i got error
PayPal gateway has rejected request. Currency is not supported (#10605: Transaction refused because of an invalid argument. See additional error messages for details) and redirect to shopping cart page.
But when i set USD currency in all my store India, global and default config and try to place order from global store using paypal payment method then successfully redirect to paypal account.
