Hello This is Suzuki from Japan.
I fail to pay with paypal express checkout.
I installed and upgraded Membership premium from Lite version, then tried to payment
in Japanese paypal and by Japanese yen.
However once I click the button, then visit to Paypal.com/jp/ , I couldn't see a correct merchant page.
Just they said "Data haven't matched the default encoding or imput letter set."
All I have to set up in membership plugin about payment of Paypal is just type my paypal account and chose Japanese site??? or should I have to do another?
(I rewrote gateway.paypalexpress.php, just put Japanese paypal site in like 'JA' => __('Japan', 'membership'),)
