The website asks for feedback. You give it and when you hit submit, it returns a red box saying:-
Actually, it’s more like an error in the error message. LOL
That error message is unusually detailed by today’s standards. Nowadays systems don’t give a lot away in error messages to ordinary users, as it can give too much information to the bad guys trying to break in. Hence you just get the “Oops, something went wrong” nonsense.
