Last week I moved to a new provider with the SMF. Everything works but only now I become the message that its not secure. Ik have installed Letsencrypts certicaat. The provider give the follow message:
Mixed Content: The page at 'hxxp:www.meatloaf.nl/forum/ [nonactive]' was loaded over HTTPS, but requested an insecure stylesheet 'hxxp:www.meat-loaf.nl/forum/Themes/classic/style.css?fin11 [nonactive]'. This request has been blocked; the content must be served over HTTPS.

I don't have a idea where I can fixed this.
Thanks for the help
