Method #1 – Change wp-content with wp-config.php
This solution is simple, but it involves editing a core WordPress file.
First, access the root directory of your WordPress installation using the File Manager in your web hosting CPanel or using an sFTP client. Then find a file named wp-config.php and open the file to edit.
Then add the following line in the wp-config file at the beginning of the file:
define ('WP_CONTENT_DIR',__DIR__ .'/lib'); define('WP_CONTENT_URL','http://yourdomain.com/lib'); define( 'UPLOADS', 'lib/uploads' );
