After modifications to your Magento store will not appear unless you clear the cache. Magento keeps its cache in /var/cache located inside the Magento installation directory.
Hence, to clear the cache, simply delete everything from the /var/cache directory and then reload your website in your browser.
In case, you want to clear all sessions, you can also delete everything from the /var/session folder within your Magento installation directory.
Note: Don’t delete var/cache folder, you need to delete inner contents.
