I have a problem in civicrm/contact/view/case&reset=1 when I use the date filter.
I have an Italian localization with date format set to dd/mm/yyyy.
I choose a date in the calendar and then I get the folowing error on screen:
DataTables warning: table id=case_id_2566 - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1
And if I look into DevTools I have this return from the site:
Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred. One of parameters (value: 09/04/2018) is not of the type Date
Which is not the dateformat set in localization (dd/mm/yyyy) but probably the default (mm/dd/yyyy)
