Interactive online tutorial fails to load

[belgoros]

I tried to load the interactive online tutorial in Chrome and Firefox on macOS, - both were failed to load, the windows were overlapped and the button"Start Scenario" had no effect:

There were no errors in the browser's console either. What is wrong with that?

I can only reproduce this error when disabling JavaScript in my browser, which is what I suspect to be the problem here.

@belgoros Do you have JavaScript disabled?

I just tested it in Safari on MacOS and it's working fine for me, but if JavaScript is disabled, I'm sure it won't work. That site is highly dynamic - the entire tutorial is an interactive client-side experience backed by a remote VM.

@picatz Nope, I never disable JS on my dev machine as I'm doing a lot of JS dev. Weird enough, - coming this morning and retrying it again raised no more the issue and I could see the login page. After logging in with one of the provided access API, I could access Katacode page. I'll close the issue. Thank you, guys, for your rapid feedback.
