    I have tested you form and I got same error.

    You have to make sure that you have enabled PayPal express in your Paypal account, please review this guide:

    The security error also means that the information you provide in the Payment configuration is not correct, please make sure to input the correct API details, also review this guide:

    Copy the whole API details in your Paypal account and paste it in your text editor such as Notepad then Copy/Paste it from there in the configuration window.

    Hope this will help. Let u know if you need further assistance.
