Your problem
I have for many years hidden field SELECT in forms linked to contact preferred_locale.
default value is set to en and when customer complete form in eanglish language preferred_locale is set to en language.
After update lates 3.X can’t set up Select field and link to preferred_locale anymore. No mather what I do it always set first language af.
These errors are showing in the log: no errors.
Steps I have tried to fix the problem:
I set select field linked to preferred_locale with default value en. YES Use assigned contact/company field’s list choices.
I set select field linked to preferred_locale with default value en with. NO Use assigned contact/company field’s list choices.
Is there any solution, or only through campagin is posible to set preferred_locale after update?
P.s.
Old forms from before update still correctly asign preferred_locale to form default value.
