I am changing the paypal account that is receiving payments by my custom button script that has worked for 5 years now. I re-generated a new private-key and public certificate (containing the alternate email). I've uploaded the public certificate to (the receiving) paypal and downloaded paypals certificate.
All files are correctly pointed to in the env: (see my script)
Openssl has been sufficient for my site for years without using their program(s)... What is going on, does anyone know why I am receiving 'error decrypting certificate id' after updating everything????
Thanks in advance!
