Black image container

Hi,

The image rotator, that is integrated in the theme “Football Club” by Themeboy, shows a black image container. The console contains the following error:

Uncaught TypeError: $(…).rotator is not a function
(anonymous function) @ (index):397
(anonymous function) @ (index):400

This error refer to the following script:

(function($) {
$(‘.image-rotator’).rotator({
‘delay’ : 4000
});
})(jQuery);
