Just got this email from the control panel

solidcp 8/5/2017 7:23:00 PM Failure: LETS_ENCRYPT_INSTALL:Object reference not set to an instance of an object.; at SolidCP.EnterpriseServer.WebServerController.RenewLetsEncryptCertificate(SSLCertificate certificate)

JUst accessed Solidcp, with the idea of manually renewing the ssl, but there’s no Button to renew… under ssl/new certificate  says:

A certificate is already installed on this website. You can create a new request or upload a new certificate, however the current certificate will be removed. If you need to renew the current certificate, click the renew button on the Installed Certificate tab.

How can we renew this ssl?
