    Thank you for your help with my event registration. I was able to fix the API credentials. But now when I try to register it says, “Security error” Security header is not valid.”

    What does that mean? How do I fix it?

    That means there is something wrong with your API keys. I see you have space before the API Username, I've fixed that. Would you mind trying again?

    Here is what it said this time as I tried to checkout. 

    Invalid Configuration
    This transaction cannot be processed. The merchant's account is not able to process transactions.

    The error message indicates that there is an issue with the PayPal account. Generally, this issue occurs when the PayPal account is not a business account or not enabled to receive the direct payments. We request you to check with PayPal support for any help in this regard.
