Paypal Error while using this plugin

Hi,

I’m getting an error:

PayPal error (10002): An error (10002) occurred while processing your PayPal payment. Please contact the store owner for assistance.

after my recent WOOcommerce Update. Please help! This doesn’t allow me to to use the Paypal Button on the product or cart page. If I click the button, it shows as though it is connecting to paypal and re-directs to the same page with the above error.

My log file shows the following code:

06-05-2020 @ 15:33:33 - WC_Gateway_PPEC_Client::_request: remote request to https://api-3t.paypal.com/nvp with params: Array
