Let's Encrypt ACMEv1 protocol. You should upgrade to an ACMEv2
Hi, i got email:
Beginning June 1, 2020, we will stop allowing new domains to validate using
the ACMEv1 protocol. You should upgrade to an ACMEv2 compatible client before
then, or certificate issuance will fail. For most people, simply upgrading to
the latest version of your existing client will suffice.
I have wordpress oneclick installation. Anyone to guide me how should i do that?
