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.

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.
