In the Pull request : i understand imiting by language : 500 quota X 4 languages : 2000 quota tested.

But i don't understand $bAllHidden : the purpose is to apply quota only of all questions are hidden. Here it's done if one questio are hidden.

We have a feature request somewhere about a new settings in quota Forced quota : No (never check without POST value) | auto (only if all questios are hidden) | force (Always check quota).

eg:
q1:1
q2:1
q5:a

not quota

@DenisChenu

Seems to be an issue : q5 must be in bPostedField .

1. In my opinion : it's another issue
2. I like to check in 3.X if we have same issue

No issue : when q5 is in $_POST value hq4 is not set.

The 2 question can be hidden, quota is checked if all question are hidden or when one question is in submitted page.

Update this can broken existing survey

See discussion about such feature (quota enforced even if no $_POST) here : https://bugs.limesurvey.org/view.php?id=11597#c40585

Maybe just
0 => disable
1 => default ($_POST or all hidden)
2 => forced : do it at each page even if not post or hidden

But on 4.3, I did not find the setting you mentioned

It not exist : it a new feature candidate.
