Drupal : Views slideshow does not slide

Recently I have just install Views slideshow module into one of my Drupal side, I am sure I have configured correctly - but it DOES NOT slide ! Even it is working fine my another site !

I scratched my head for a week, until the light is brought by one of my good friend. He said,

Disable Devel module, seems like jQuery goes wrong somehow when this module is on

Thanks to Mr.Yuttana ! it works like a charm, woopie !!!
