How to fix warning: AutoSSL is disabled

[chrisg]

After updating to CWPpro version: 1.26, I get the following new warning on the dashboard:
1 item need attention: AutoSSL is disabled
When I click on it, I get the error "The module autossl does not exist."

All my domains use "Let's Encrypt".
When I go to "Web Server Settings" - "SSL Certificates", all certificates look OK.
Clicking on "Renew now" for a certificate also works, and then shows 89 days left, so the renewal worked.

Is this warning just a false positive?
