Thank you for your help. When I click on Save Changes, all is OK.

When I go to settings and Field settings there is no field and:
“No Field Selected
Please click on a field in the form preview on the right to change its properties.”

Your code is OK, I try it on another site.

Sorry, but the calculator is gone and paid options are available. Did you make any changes to the site?

Thank you, but it did not work. But its not so big problem. ??
I change notice, but when I insert invalid date, notice is still in English.

Yes, its work. Thank you.
Can I change dates format? I try this:
dateFormat: ‘dd.mm.yyyy’,
Date is still dd/mm/yyyy.

Many thanks for the answer.
I try 2 files:

jQuery(function($){

$.datepicker.regional[‘cz’] = {
closeText: ‘Fermer’,
prevText: ‘<Préc’,
nextText: ‘Suiv>’,
currentText: ‘Courant’,
monthNames: [‘Janvier’,’Février’,’Mars’,’Avril’,’Mai’,’Juin’, ‘Juillet’,’Ao?t’,’Septembre’,’Octobre’,’Novembre’,’Décembre’],
monthNamesShort: [‘Jan’,’Fév’,’Mar’,’Avr’,’Mai’,’Jun’, ‘Jul’,’Ao?’,’Sep’,’Oct’,’Nov’,’Déc’],
dayNames: [‘Dimanche’,’Lundi’,’Mardi’,’Mercredi’,’Jeudi’,’Vendredi’,’Samedi’],
dayNamesShort: [‘Dim’,’Lun’,’Mar’,’Mer’,’Jeu’,’Ven’,’Sam’],
dayNamesMin: [‘Di’,’Lu’,’Ma’,’Me’,’Je’,’Ve’,’Sa’],
weekHeader: ‘Sm’,
dateFormat: ‘dd/mm/yy’,
firstDay: 1,
isRTL: false,
showMonthAfterYear: false,
yearSuffix: ”};
$.datepicker.setDefaults($.datepicker.regional[‘cz’]);
});

Files name is cestina-datum.js

I tried too original (from your site with “fr”), but it did not work.
Thank you.
