Paypal Upgrade to SHA-256
I am using Classipress 3.5.1 with WordPress 4.3.1.
I have received an email from PayPal stating:
PayPal is upgrading the certificate for
www.paypal.com to SHA-256. This endpoint is also used by merchants using the Instant Payment Notification (IPN) product.
This upgrade is scheduled for 9/30/2015; however, we may need to change this date on short notice to you to align to the industry security standard.
You’re receiving this notification because you’ve been identified as a merchant who has used IPN endpoints within the past year. If you have not made the necessary changes, we urge you to do so right away to avoid a disruption of your service!
Can anyone tell me what the "necessary changes" are? Do I need to do anything in my Classipress settings?
Thanks
