The former means off-turn-CG gives you 1 action, and that action has no effect (whatever that might mean);
It means it doesn't let you play Actions on your opponent's turn. Which, as it turns out, is what it means.
Playing this during another player's turn is similar to playing it during your own turn - you put Caravan Guard into play, get +1 Card and +1 Action, and will get + at the start of your next turn - the very next turn you take. However getting +1 Action during someone else's turn does not do anything for you; it does not let you play other Action cards during that player’s turn.

The part that is 'confusing' to me is the
"... get ... +1 Action, ... the very next turn you take ..." It makes it sound like you get ANOTHER "+1 Action" on top of your default ABC "+1 Action" on the very next turn you take (like an unspent +1 Villager token on your mat.. it is waiting for you to 'use' ... on 'the very next turn you take'. It seems opposite of the fact that you get you use the +1 Coin on your next turn, but you cannot use the +1 Action?
You're grouping the wrong words together; missing where the word "will" comes in the sentence.
It's "(get +1 Card and +1 Action) and (will get +
at the start of your next turn - the very next turn you take.)"
It is not "(get +1 Card and +1 Action and will get +
) (at the start of your next turn - the very next turn you take.)"
The "will get ... at the start of your next turn" is only referring to the +
. This is exactly the same as playing a Caravan normally. When you play it normally, you get +1 Card and +1 Action right now, and you get +
at the start of your next turn. You don't get all 3 at the start of your next turn.
