Timepicker – do not display

I have installed this plugin and do not want to display the timepicker section in the calendar.

I tried the following:

– [datetime* start-date date-format:dd/mm/yy showTimepicker:false]

however, this may no difference, the timepicker still showed in the calendar.

Can you please let me know what I need to do?

Thanks!
