IF You are seeing the PayPal web-page saying:
[Return to Merchant]
‘This feature is available for Business Accounts Only’ …and the ‘MERCHANT’ button
…is because You need first to validate you Email Address before proceeding to CHECKOUT !
No worries, you won’t lose any data you have entered and you order has been stored in our system.
After you validate your email address following that link received into your inbox, you will be able
to proceed to Checkout and make the payment having the option to go for PayPal or 2Checkout gateway.
Thank you !
