Hiya
I have just set up a LetsEncrypt cert on a dnn8 site.
Things work as expected except any images in html modules which seem to be fetched over http resulting in the "Not secure" chrome warning.  (Grrr)
Does anyone know a remedy please.  
Thanks

Betacam,

You have different options. One could be to replace all occurences of "http://www.mysite.com/" by "https://www.mysite.com/" in the HTML modules using SQL, something like

  UPDATE HtmlText
  SET Content = REPLACE(Content, 'http://www.mysite.com/', 'https://www.mysite.com/')
  WHERE Content LIKE '%http://www.mysite.com/%'

Or, even better, get rid of the protocol and server part:

  UPDATE HtmlText
  SET Content = REPLACE(Content, 'http://www.mysite.com/', '/')
  WHERE Content LIKE '%http://www.mysite.com/%'

This could be a pain, esp. if you have other modules than HTML that display such images, or use links to stylesheets or Javascripts etc. with this syntax.

The better way would be to implement a Content Security Policy, there you have the option to upgrade insecure requests by the browser automatically (will not work in really old browsers, but they don't care about mixed content anyway...)

See

Happy DNNing!
Michael

Betacam,

you're welcome, I am glad I could help. What I should mention: After touching the database you should restart the application pool. Otherwise you could get cached data, and your changes could not be reflected on the web site.

Happy DNNing!
Michael
