My corporate website is completely safe and the certificate also, but it seems I can't show you screenshot showing this...
There's only small content related to blockchain...

Very happy for me not living in euro zone...

I've just tried also with a VPN located in Netherlands, it works...

Maybe you could try with a VPN and see ?

Sorry, I have a VPN but it's still located in our totalitarian country. Anyway, there is no bug in the course menu I know of.
There are plenty of ways to upload images or to link to them. Alfa24 has asked you to describe the steps to reproduce the issue and we still didn't see anything. I am closing the topic.
