"404 Invalid chess color" when trying to open any game

When looking at the opening database and you click on any game I get this message:
____
404
PAGE NOT FOUND!
Invalid chess color, should be white or black
____

This happens when trying to open any game link from opening explorer. I'm using Google Chrome btw.

It is true this is a serious lichess problem I hope they solve it soon

I am having this problem as well

They fixed it!
