I was converting a regular WordPress blog to a Multisite blog the other day. I got stuck in the part where I needed to edit the wp-config.php file. I applied the changes to wp-config.php as suggested in the installation instructions. The problem was I wasn’t seeing the Multisite menus you would normally find under ‘My Sites’ inside the WordPress Dashboard. The installation instructions tells you to add the following lines to your wp-config.php file.
/** Enable WordPress Multisite */
$base = '/';
It was a silly mistake on my part. I placed these entries at the end of the wp-config file. It is important that these lines remain above the absolute path statement and before the wp-settings are loaded. See below.
/* That's all, stop editing! Happy blogging. */
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') ) define('ABSPATH', dirname(__FILE__) . '/');
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
Keep these lines at the end of the wp-config.php file.
