Fields "Recurring days" and "Expires at" don't work correct


I realize that fields “Recurring days ” or “Expires at“ in user profile don’t work correct. If I enter a value (for example, one day) in the field “Recurring days », nothing happens (user can still not read the locked posts).

And the field “Expires at” seems faulty too. Actually, I should be able to enter a date which lock the post by schedule. But, that doesn’t work too. I can enter a number or a letter and the post will be unlockt both times.

Can you check this please?
