I am using the latest version of Chrome.
I am going back and trying to complete new lessons in sections I had already completed. When I click the View the Curriculum button I often get a blank page. I have to reload the page and try again. Some times I get blank page when I click the expand arrows in the modal window. About every third time, when I go to reload the page, I can’t and have to open a new tab for Freecodecamp.org and start at the home page.
