VM55:6 Mixed Content: The page at 'xxx' was loaded over HTTPS, but requested an insecure script 'http://changyan.sohu.com/upload/changyan.js'. This request has been blocked; the content must be served over HTTPS.
When I use Changyan comment plugin, the url was http, my browser noticed me an error.
At present, Changyan is already support https.
So, I update it.
