I've tried again and again and again. Searched the web too for help but I finally decided to seek some help here. Thanks in advance.
The problem is:
I've carried out a fresh installation of WP 3.5 in my localhost. Everything is fine. However, when I tried activating multisite on this installation by adding "define('WP_ALLOW_MULTISITE', true)" to wp-config.php, "Network Setup" doesn't appear under "Tools" menu.
Clueless here. Please help me out.
