When you're making changes to Magento, it's necessary to disable the Magento cache. The cache is a tool Magento uses to quickly remember how your store is structured through a condensed summary of all the settings in your store.

You can disable the Magento cache by going to System | Cache Management. There, click on Select All and click on Disable in the top-right corner of the screen. Finally, click on Submit and the cache is disabled. Another way of cleaning Magento's cache is by logging into your FTP server, and clearing the contents of the var/cache folder. The cache management section of Magento's admin is shown in the following screenshot:
