If you have a PayPal account, you’ll likely be getting an email from them talking about upgrading their SSL certificates. You can see PayPal’s full announcement here.
You’ll likely ask, what does this mean for me? The short answer is Zen Cart software is not affected by these changes. But that does not mean you can delete the email and forget about it. According to Zen Cart, ‘to communicate with any payment service DOES require that your server have a working SSL infrastructure in the back-end. This is almost always already present, but isn’t always up-to-date.’
