An hour ago paypal informed me, that “at any time between now and end of September” the certificate for http://www.paypal.com will be updated to SHA-256. This would (so they say) affect the usage of the IPN.
At checkout MarketPress uses the IPN mechanism to find out, if the customer has actually paid with paypal (right?).
So my question: Is my store affected by this certificate change?
Or should I rather ask this question my web hosting company (which presumably is responsible for the certificates used by the server where my store is hosted)?
Thank you for any hints!
