Comment:

 Replying to [ticket:48817 felipeelia]:
 > `_deprecated_hook`, the function responsible for logging an error when
 an old hook is called, uses `is_null` to check if a `$replacement` was
 provided.
 >
 > The problem is that `$replacement` defaults to `false` (instead of
 `null`) on `apply_filters_deprecated` and `do_action_deprecated`,
 displaying the `Use %3$s instead.'` message without any value.

 Hi,

 This ticket looks interesting. Can you please provide any screenshot or
 the hook that is causing the issue?

 Thanks.
