    Hi @BGF,

    Sorry to hear of the problem you are having.

    You are using Paypal in sandbox mode so please make sure that you are using Paypal sandbox details and not Paypal live mode details.

    Usually this error happens when you are using an incorrect email address. So, kindly check if you've entered the correct details. Also, happens if you are having an unverified email address so please kindly check as well.

    The payment email for receiving payment might be on a personal account. Upgrade it to Business account.

    Would you mind if I logged in to your site and did some troubleshooting? This might help get to the bottom of this faster. If this is ok, just grant me temporary admin access to your site by clicking "Grant Access" button in the WPMU DEV Dashboard Settings as described on the following page and reply on this thread after granting it?

    Kind Regards,
    Vinod Dalvi
