and PayPal have both made recent changes to the protocols they accept for processing credit card orders. As a result, many Zen Cart sites will suddenly find that people cannot check out as their credit cards will not process (we are seeing this happening a lot in Q1-Q2 2015)

This will happen to any site where the SSL is running SSL 3.0 or TLS 1.0.
