Can't continue with a lesson

Hello. I am attempting to resume a lesson,but whenever I click resume, it just refreshes the page.

Refresh the page and try again. If it does not work go to the Resume button Make a right click with your mouse. And select open in a new tab.

Already tried that. Another thing is that I lost progress on the rest of my ongoing lessons, and when I click on resume java, it redirects me to resuming making a website.

EDIT: I got it to resume, but now my problem is that it is not saving my progress

Am having the same problem! HTML course.

Also happening to me D-:
