JS error on theme setup

Hi

Jquery error but not sure about studio.

I have this error :

GET http://hippocampe.passion-cheval.net/wp-content/plugins/inc/js/effects.core.js?ver=3.2.1 404 (Not Found)

And of course the theme options does not work properly.

And found this answer :

http://wordpress.stackexchange.com/questions/7221/how-to-correctly-include-jquery-ui-effects-on-wordpress

telling that the librairy the UI/Effects library is not included by default.

Need to add

wp_enqueue_script('jquery-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js', array('jquery'), '1.8.6');

somewhere but no idea of WHERE !

Any tips ?
