Hey there!
(I believe the present post is not a duplicate of “Paypal subscription”.)
I have been trying to upgrade my subscription plan from monthly to annual using my credit card. However, when I click on the “Upgrade Bunrpo: yearly” button, the BP website tries to access this url : https://www.bunpro.jp/subscriptions/upgrade_subscription , and my navigator returns me an “http 500 error”.
Any clue?
Thanks
