PayPal has announced several security updates set to roll out in 2016 which will impact sites using PayPal gateways. This post covers the TLS 1.2 and HTTP/1.1 upgrade scheduled for June 17, 2016. If all actors involved (your host, WordPress, Paid Memberships Pro, and PayPal) update before June (we plan to), you should experience no disruption in your service. However, if you are using the PayPal sandbox environment now or otherwise want to make sure your host and website are ready, please review the content below.
We’ve outlined the steps to take now to ensure compatibility and avoid a disruption of service.
