Hi n_l1
Have you tried different strings for DateFormat? Maybe your configuration needs a different string buildup to recognize date-types such as "d-MM-yy" or "yy-MM-d".
When you change this, the date-inputfield should match with the datebuildup which you've entered in de datepicker.php file.
Important is that when you enter a new event is to look whether the day and the month don't get mixed up.
