A lot of people are getting these notices in their email. If you’re using WooCommerce with Paypal integration, there is no need to worry about WooCommerce. However, you should check with your hosting provider to make sure that they are up to date as well.
Mike Jolley, one of the plugin authors, posted this notice:
“The WooCommerce PayPal Standard Gateway itself requires no changes. You should however check that your hosting provider supports the new certificates.”

Siteground hosting is ready for the upgrade, so if you have them, no worries for you. I have a customer with GoDaddy. They said that if you have a new SSL, you are fine, but if you’ve had it for a while, you’ll need to call them and have them “re-key” it to SHA-2.
As always, probably a good idea to do a test once they change over to make sure, but for now, no need to worry about Woo. Just call your hosting provider and make sure both the hosting and the SSL certificate is good to go.
Is your host ready? I’d love to hear from you in the comments section.
