Thanks all guys!

My problems are on MySQL server and database, for some reason, the installation process could not create database.(prefix)config table (punbb.cptconfig), then PunBB could not fetch configuration for forums. Now, problem are solved: I did remove old database then created a new one, do installation process one again and any thing is done now.

Thanks again!

I have to do all step required to install punBB, at the end of install process, I did create config.php base on script:
<?php

$db_type = 'mysql';
$db_host = 'localhost';
$db_name = 'punbb';
$db_username = 'root';
$db_password = '';
$db_prefix = 'cpt';
$p_connect = false;

$cookie_name = 'punbb_cookie';
$cookie_domain = '';
$cookie_path = '/';
$cookie_secure = 0;

$language = 'en';

define('PUN', 1);

?>

BUT when I try to load index.php. my browser returned: Unable to fetch forum config.
How can I solve this problem??
Thanks for your help and sorry about my English!
Best regard!
