I edited the catalog.xml file but still NOT working !!
Folder: /app/design/frontend/base/default/layout/catalog.xml
Code Removed:
Line 56 <block type="catalog/product_compare_sidebar" before="cart_sidebar" name="catalog.compare.sidebar" template="catalog/product/compare/sidebar.phtml"/>
Line 166 <action method="unsetChild"><name>catalog.compare.sidebar</name></action>
QTN: Is it the correct Folder ??
base/default is basically a core package/theme. Modifying it is generally considered a Bad Idea. Also, it's usually just a fallback of real theme, such as rwd/default (Magento CE 1.9) or default/default (earlier versions). Modifying your own theme or better yet, using local layout update file (local.xml) is highly recommended.
Simplest way perhaps is to use remove command.:
<layout>
<default>
<remove name="catalog.compare.sidebar" />
</default>
</layout>
Please note that means that the sidebar is removed from ALL pages.
Never edit the base theme files!
Use an local.xml in your theme (pathtoyourtheme/layout/local.xml)
<?xml version="1.0" encoding="UTF-8"?>
<layout>
<default>
<action method="unsetChild"><name>catalog.compare.sidebar</name></action>
</default>
</layout>
<remove name="catalog.compare.sidebar"/>
add this line where you want to remove.
<reference name="left">
<remove name="catalog.compare.sidebar"/>
</reference>
<remove /> works at the layout level, so it never belongs in a <reference />
