Custom HTML widget doesn’t display

What is the code? Would you please provide use Pastebin or a Gist to share it here?

Here is the pastebin link

That code includes a script. Is it being served from the same domain as your site?

No, it’s not. I found out the reason, my old website is http and the new one is https, the old site is displaying without any problem but the new one is blocking it, saying: “this page is trying to load scripts from unauthenticated sources”. I guess, there’s nothing I can do with this right? I really need this widget

Yes, that’s the problem. You can’t embed HTTP scripts from an external domain on an HTTPS site.

Thank you for you reply
