I've done that before, there's no effect. You mean the settings of the Slider, don't you?

Open browser's error console and you we will see it contains javascript error. The error is not related to "ARI Orbit Slider" extension, but it prevents execution of "ARI Orbit Slider" javascript code. It seems the error occurs because MooTools library is removed by a 3rd party extension or by site template, but javascript code which uses MooTools is not removed (this code can be added by Joomla! or 3rd party extension). Fix the error and the slider should work fine.
