Date-Time Picker not working | WordPress.org

my form is not accepting any date/time entry – saying “it “the date format is incorrect” when it is not!!

i have only 1 rule – preventing past dates – but even switching this on or off produces the same error

even changing the setting to “date only” – i still get the same error

changing the date format – same error

why is it telling me the date format is incorrect when clearly it is ?!!

please fix this asap
