Slider doesn't work with java-script error on the front-end right after installing MageRewards on my custom store design
You may see an error like this if you have custom JS includes on your store:
Control is not defined in SmoothSlider.js (line 46) -> SmoothSlider.prototype = Control.Slider.prototype;
right after this:
<block type="page/html_head" name="head" as="head">
in your page.xml file that is being loaded to resolve the issue.
