Problemas com Session no Servidor

Galera acho que o session não está habilitado, vê se alguem pode me ajudar

entrei no painel e vi isso

Olha o erro em meu site

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /admin/index.php:1) in admin/index.php on line 1

Essa parte de baixo da configuração do meu php quer dizer algo sobre session né?

main

session.save_path

where N is an integer. Instead of storing all the session files in /path, what this will do is use subdirectories N-levels deep, and store the session data in those directories. This is useful if you or your OS have problems with lots of files in one directory, and is a more efficient layout for servers that handle lots of sessions. NOTE 1: PHP will not create this directory structure automatically. You can use the script in the ext/session dir for that purpose. NOTE 2: See the section on garbage collection below if you choose to use subdirectories for session storage

N;/path
