Still solved Projects gone after redesign

I had still solved some JS-Projects… and they have an green check on the overview:

But if I click on one of them (e.g. Palindrome Checker) there is no code inside. It is the unsolved Project.

So what did this mean for certification? Have I to repeat all projects now?

If they have a checkmark, then they’re not gone. There are solutions associated with your account. If you look at your public portfolio page, you will see all of your completed challenges listed. There is a bug right now that causes the ‘view solution’ button to open a blank page, but that’s being worked on.
