Using Paypal IPN and SSL. Activating it in the CP Admin.
My ClassiPress System Info screen says the following about FSOCKOPEN.
Your server supports fsockopen so PayPal IPN should work. If not, make sure your server is SSL enabled and port 443 is open on the firewall.
Unfortunately this explanation is a bit vague. How do you "enable" SSL? I know my server is capable of SSL. Is it enabled? I don't know. Or is that phrase making a suggestion that if paypal IPN doesn't work, then check to make sure SSL in enabled?
Bottom line: My server supports fsockopen so can I start using paypal IPN?
