Introduction to CSS not working - Never mind

Hi guys,

I can get the title page of Introduction to Basic CSS to load, but I can’t get any of the lessons to load. I don’t think it’s me as HTML was fine, and if I skip ahead to another top that works fine too.
Could someone tell me if it’s the website or me?
If it is the website, how do I report it? I can’t find a contact us page on the website.

Cheers all,

Turns out a hard refresh with ctrl, shift and R fixed it.
