    Hi guys,

    Awesome plugin! Pretty much all the functionalities are working great. But only when I add a payment (PayPal Sandbox, configured properly with API key/signature) and the invoice is sent via email and the PayPal button is clicked, it goes to the following URL:
    https://wpfree.devhtmlfive.com/payment/ (which is our test site and the payment page is created by the plugin) and every time we get the following error:

    Error Code: 10002
    Security header is not valid

    The page I need help with: [log in to see the link]

    “Error Code: 10002 Security header is not valid” is a PayPal error, it means the API keys are not correct. I recommend you check the following:

    1) Make sure you are using only the NVP/SOAP API keys from PayPal. (NOT the REST API)

    2) Make sure the keys you’ve entered match the “PayPal Mode” setting. If “PayPal Mode” is set to “Sandbox”, you must enter the Sandbox keys. If “PayPal Mode” is set to “Live”, it must be the Live keys. (Your Live and Sandbox keys will be different.)

    3) Make sure there are no extra spaces before or after your API username, API password, or signature.

    Hope that helps!
