I have completed upto pset2. But after the course upgrade I can neither view the Cs50x 2017 material nor the older CS50x 2016 material. Are they still updating their servers or is the problem here on my side?

Whenever I click on CS50x 2017 link the page scrolls down and the same happens if I click on any of the "Week N" links and CS50x 2016 link.

Are you using an ad blocker? I use firefox w/ABP and no videos would play until it was disabled for edx.org. You can also find the class materials for CS50x 2017 here, the Harvard fall 2016 version.

  • thank you very much for helping. I had exactly the same problem as you stated. Commented Jan 8, 2017 at 14:35
