After upgrading from version 3.11.2, save form

Klas and sebastienheraud, The error appears when you save a record from an override form with free table if that helps!

[klas]

First try removing the override, to see if that changes anything. Also check your date format if you use written names of days or months (e.g. Friday, 26 October will only work in English).

Klas,I checked the dates fields and they were with d-m-Y for with the listing, to appear in pt-BR format, I returned to Y-m-d and did not give the error anymore, however the listing was in the Y-m-d format which is not the pt-BR format!

@klas, can you conclude here please ?
