The "Join the discussion" link on the QOTD from the 6th links off to a blog article.
There is a link to a discussion with a title of "oops" that when you click on it, brings you to today's QOTD discussion (Feb 7th, 2020).
The above is all just my opinion on what you should do.
As with all advice you find on a random internet forum - you shouldn't blindly follow it. Always test on a test server to see if there is negative side effects before making changes to live!
I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
