When I click on “Get a Hint”, I get the message: Oops! That page does not exist or is private. I do not know why this has started to happen to me. Could someone guide me to solve it?. Thank you.
Hi randelldawson. I´m working in the challenge 89.
Ahh ok! 
The name of the challenge is: Accessing Nested Objects.
I´m using: freecodecamp.org
In all the previous challenges, the “Get a Hint” button worked, but in the previous one this challenge has stopped working and instead the message appears: Oops! That page does not exist or is private. I do not know why this has changed.
Thanks randelldawson!. I will find out if there is any open debate about this challenge.
