Is it possible to replace "changed the visibility" by something more specific? As it is now, this message it too vague to be translated to something to be understood by non-experts, I am afraid.
more specific in what sense?
It is easy to say " A mode B visible and made C visible and made D invisible. " It is pretty strange to say " A made something unnoted either visible or invisble or both. " While a strict translation of "to change the visibiliy" fails due to lack of vocabulary, more concrete or more specific vocabulary in needed, such as "to make invisible" or rather "to hide", and "to make visble" or more clearly "to show".
I still don't get what is the problem with the message text. Either something is visible (=shown) to visitors or it is not.
Yeah, you got it! It is either shown or hidden. But the message does not reveal that. It translates to "X is either shown or hidden" which is exactly nothing said. Anything is either shown or hidden. Not worth to mention. Tautological.
So as as to say something useful, we need to be more specific. Otherwise, the messge makes a nice joke, but does not reveal any information.
