I cant find this url on this page it is supposed to be on but I have purged this url cache with cloudflare.

It is stating that the url is on - Cool Stuff / Quizzes to tax your brain, Jokes that will make you laugh out loud, and fun Games for the family
but I cant find it…any help please would be appreciated.
best regards Robert
