renaming wp-content

I can’t rename the wp-content
I put this in wp-config.php

define( ‘WP_CONTENT_DIR’, $_SERVER[‘DOCUMENT_ROOT’] . ‘/ibv_content’ );
//define( ‘WP_CONTENT_DIR’, ABSPATH . ‘ibv_content’ ); // no trailing slash, full paths only – WP_CONTENT_URL is defined further down

define( ‘WP_CONTENT_URL’, ‘http://ibibleverses.com/ibv_content’);
//define( ‘WP_CONTENT_URL’, get_option(‘siteurl’) . ‘/ibv_content’); //full url – WP_CONTENT_DIR is defined further up
