Cannot access Front End Libraries curriculum

While working on the Front End Libraries lessons, I could not get it to load to the next challenge. I went back into the curriculum menu and I cannot access the Front End Libraries section anymore. In fact, the top 4 sections: new Responsive Web, Legacy Responsive Web, Javascript, and Front End libraries are no longer accessible; clicking on them does literally nothing. All the other sections below can be accessed however (Data Viz, etc…) I believe the website is having a snafu.

And…it’s working again. Never mind!

Looks like there are still some issues for some users at least… my page isn’t loading properly at all. Just see the header and footer, no content / courses / etc.

I expect there is some tinkering going on atm- hopefully it will settle soon.
