Jquery UI Datepicker not displaying

Question

UPDATE
I have reverted back to Jquery 1.3.2 and everything is working, not sure what the problem is/was as I have not changed anything else apart of t

Answer 1

I had the same problem using JQuery-UI 1.8.21, and JQuery-UI 1.8.22.

Problem was because I had two DatePicker script, one embedded with jquery-ui-1.8.22.custom.min.js and another one in jquery.ui.datepicker.js (an old version before I upgrade to 1.8.21).

Deleting the duplicate jquery.ui.datepicker.js, resolve problem for both 1.8.21 and 1.8.22.
