How to remove the cufon script from Dzonia Lite theme [closed]

You can remove scripts with wp_dequeue_script():

function wpse99450_remove_cufon() {
    wp_dequeue_script( 'inktheme-confu-ui' );
    // inktheme-confu-ui is the script's handle, according to your posted code
}
add_action( 'wp_enqueue_scripts', 'wpse99450_remove_cufon', 20 );
// set priority to '20' so it will run later than the default

But be careful — as @gdaniel pointed out, if the theme depends on cufon, you will break things.
