I can not continue the 'get started learning path'.

[AnneJits]

I am not able to click attached videos/documents (no icons are visible) in the 'continuing Core Topics' section of the 'getting started Learning path'. So, I am not able to do any practise exercises in this section and it seems that words are mixed and are not really readable. 

I attached two screenshots of the error.

Can someone help me so i can complete my training?

Try a different browser.  Maybe enable Javascript?  Clear the browser cache?

If the screens work OK for another person, it's an issue with your machine or browser.
