I tried to install and set up a WordPress Network this evening. After following the instructions and logging in as the admin, the Network link is not there. I tried going directly to /wp-admin/network/ and get the message "You do not have sufficient permissions to access this page."
I'm really not sure what to do next.
I saw somewhere that someone had this problem because their web host didn't support WordPress networks, so I thought I'd ask my network administrator but I couldn't find the system requirements. This - http://codex.wordpress.org/Create_A_Network#Server_Requirements - is not particularly helpful.
Can someone point me to the system requirements for a wordpress network or provide any other help to get this working?
