LetsEncrypt is now installed on our CPanel. Below is the error message when attempting to “+ Issue Single” for one of our domains. Is there a problem with the install, or something that needs to be configured? Thanks.

While I think your question is on-topic here and it would be helpful to have an answer here, you might get a faster reply at the CPanel forum because your problem is definitely related to CPanel configuration or permissions in some way.
The error message suggests “SSL Host Installer” is not enabled for the feature list associated with the package assigned to the account. You can enable this feature via “WHM >> Packages >> Feature Manager”.
