temporary solution till the plugin gets fixed:
make all the modifications you want to KK i Like It plugin settings in the admin panel, then comment this line in /plugins/kk-i-like-it/admin.php :
//add_action(‘admin_enqueue_scripts’, ‘kklike_admin_enqueue_scripts’);
this will prevent loading the buggy javascripts in the admin panel, but the plugin still works fine at the frontend.
