If you would like to hide the left-hand bar for static pages only, but still want it displayed for other pages, just follow the below guide.

Step-by-step guide

Here are the steps involved:

1. Install and activate "Custom Skin" module

2. Create the following custom script in your X-Cart installation:

   classes/XLite/Module/XC/CustomSkin/Core/Layout.php

3. Add the following code to the custom script:

   <?php
   namespace XLite\Module\XC\CustomSkin\Core;
   class Layout extends \XLite\Core\Layout implements \XLite\Base\IDecorator
   {
        /**
        * @return array
        */
       protected function getSidebarFirstHiddenTargets()
       {
           return array_merge(
               parent::getSidebarFirstHiddenTargets(),
               array('page')
           );
       }
   }

4. Rebuild the X-Cart cache.
