Instalação do phpbb2

[jonhy10]

Depois de dizer que consegui fazer a instalação básica do phpbb2, aparece isto:

Fatal error: Call to undefined function: session_pagestart() in /home/www/ocabula.awardspace.com/includes/functions.php on line 579

A função session_pagestart() não está definida, ou seja, você no meio do código chama uma coisa (a função) sem antes dizer o que aquela coisa (a função) vai fazer.

Achei isso:

http://www.suportephpbb.org/forum/viewtopi...cc6e23ed353804c

http://mais-trafego.info/comunidade/viewto...b56751ccd1e5903

[jonhy10]

Mas eu não percebo, porque tenho o mesmo entre os parenteses que os tutoriais: $userdata = session_pagestart($user_ip, PAGE_INDEX);

O que eu fiz foi o seguinte:

Fiz o download do phpbb2.

Coloquei dentro de uma pasta X no servidor e executei o install. Apareceu que tinha instalado com sucesso, cliquei em terminar instalação e apareceu

Fatal error: Call to undefined function: session_pagestart() in /home/www/ocabula.awardspace.com/includes/functions.php on line 57

O que é que posso fazer?

[ESerra]

Ai tem um cara que tem um problema como o seu e disse que tem uma chave a mais. Eu não li todo o tópico, mas por ter 40 páginas, deve ter a solução.

[jonhy10]

Obrigado pelas respostas. Consegui resolver o problema. Agora sabem-me dizer como é que ponho o forum ao meu gosto? As secções, o título, logotipo, essas coisas?

Muito obrigado.

P.S. Alguém sabe porque é que quando eu clico em logar e em sair do user a página vai para a página do servidor? Mas quando vloto para o forum o que eu pedi está certo. Estar logado ou não

Eu li sobre esse problema em algum lugar... isso dai é o "header(location...)" que está com um bug... mas não anotei a solução para o problema...
