Erro

[Guilherme Henrique]

modifiquei o arquivo configuration.php para colocar o site no ar.

mas apresenta a seguinte mensagem

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Inetpub\wwwroot\site.com.br\httpdocs\configuration.php:1) in C:\Inetpub\wwwroot\site.com.br\httpdocs\libraries\joomla\session\session.php on line 412

onde pode estar o erro e onde devo modifcar para resolver o erro?


considerando que meu site é "www.site.com.br"

Obrigado
