When checking out from my site the only option I provide is PayPal. This used to work fine.
Now, when you get to the end of an order and click the confirm order button, you get sent to:
https://www.paypal.com/cgi-bin/webscr
and get an error:
The certificate has expired. Please use a valid certificate.
----------------
The url bar of IE is green, the certificate is shown as verified by Versign as PayPal.
I installed the Versign PayPal certificate to my browser. No help.
Any ideas what I need to do?
I have neglected my osC site for a while and now trying to get back up to speed.
Thanks,
