Good day @Eventually127, Thank you for posting to the PayPal community. By default, you accept payments from encrypted and unencrypted buttons. For additional security, you can prevent buyers from sending payments to you through unencrypted buttons. After you change this setting, we reject payments from your buyers who click an unencrypted Buy Now button, an unencrypted Donation button, or an unencrypted Subscription button. If you previously blocked payments from unencrypted buttons, here’s how to accept all payments: Login PayPal.com > Settings > Account Settings > Website Payments > Website preferences > Encrypted website payments > Block non-encrypted website payment >> select “Off”. Once the above settings is turn "off", you should no longer receive the error message. If your still facing any issues, please create a MTS ticket via - https://www.paypal-support.com/s/?language=en_US with the detail information and error details. Sincerely, Chiranjeevi PayPal/Braintree MTS If this post or any other was helpful, please enrich the community by giving kudos or accepting it as a solution.
