Hi @leslieannetd,
Nonce validation occurs in many places and by this error alone is difficult to pinpoint. Could you share with us a copy of your WooCommerce system report so we can learn a bit more about your site?
If you can reproduce this error, you may also want to perform a full conflict test to rule out eventual issues with the theme or a different plugin. We recommend temporarily activating the default theme Storefront and disabling all other plugins except for WooCommerce and PayPal Payments to see if the behavior persists.
Here’s a guide that explains the steps in more detail:
How to test for conflicts
Please let us know how that works out for you. Thanks!
Kind regards,
Niklas
