  • How was Ghost installed and configured? Digital Ocean
  • What steps could someone else take to reproduce the issue you’re having?

So, I was trying to add the Gtag, which I initially configured with wrong website address (added extra www to the site address) and added the snippet to the Code Injection. After that the website has been showing SSL error. I realised the error and configured with the correct address, even then it is showing the SSL error on Chrome.
