Glitch website randomly giving "Well you found a glitch"

It started happening today, when I was on my website ( nothing was wrong, but after a while it started giving the error (well you found a glitch) in random times… Can someone tell me if it is just me or if it is a code problem?

Btw it works after a refresh but it still happens after browsing the website for a while.

I don’t have any error in the logs.

Sorry if bad english :+1:
