Hello – just letting you know I’m still looking into it.
In the Google Chrome security tools I’m getting a clean bill of health for every page that people have mentioned in this thread so far:
I can only think that the latest update to Chrome on Windows (I’m running the latest update on Ubuntu) is reporting something as erroneous, possibly by mistake if the same version has no issues on other devices. I’ve had a look through the source for the page and there are a couple of references to HTTP URLs – they shouldn’t affect anything as they’re not part of any mixed content or forms, however it’s possible that Chrome on Windows now thinks that’s an issue.
I’ll keep investigating and I’ll look into removing any HTTP URL references from the pages’ source – that’ll be a bit of a deep dive, though, so it won’t be immediate.
In the meantime, any more information would really help – I can see some of you have already posted some more, thanks so much for that!
