Paypal authentication problem !

[DrByte]

But whats the deferent between the other two Paypal methods ? where it shows :

- Save time. Check out securely.
Pay without sharing your financial information.

- Checkout with PayPal. The safer, easier way to pay.

One is Website Payments Standard, and the other is a different entry point to Express Checkout.

what was/is the solution to this problem?

We are sorry for the inconvenience. The PayPal account authentication settings are not yet set up, or the API security information is incorrect. We are unable to complete your transaction. Please notify the store owner so they can correct this problem. (10002) 10002 Security error - Security header is not valid
