I think this problem is caused by some code somewhere being hardcoded with http scheme instead of looking at the current session’s scheme. i.e. http and https are being used when only https should be used.
If you try use the editor on IE, you get the message “Only secure content is displayed”. If you press “Show all content”, the page refreshes and the editor is now useable. When you use Chrome, there is no error and the editor is not functional.
I have attached a screen shot of the IE error message and how the editor looks when it fails and a shot of the Chrome console.
I have seen this problem on several sites where IE works but Chrome doesn’t. It’s unusual that IE works and Chrome doesn’t ๐
I hope this helps you Ed?
Cheers,
Ian
