No board, but I've installed..

Are you sure the information in your config is entered correctly? The PunBB-zip-file contains an example file, compare your file with that one and see if something's wrong.

Hmm, still no luck.

I've got two boards on the same domain.. so I guess it'll be on the same database.

The one that is working, the config.php looks like this:
<?php

$db_type = 'mysql';
$db_host = 'localhost';
$db_name = 'chibidragon_com';
$db_username = 'chibidragon_com';
$db_password = 'password';
$db_prefix = '';
$p_connect = true;

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

$language = 'en';

define('PUN', 1);

And the one that is not...

<?php

$db_type = 'mysql';
$db_host = 'localhost';
$db_name = 'chibidragon_com';
$db_username = 'chibidragon_com';
$db_password = 'password';
$db_prefix = 'WQ';
$p_connect = true;

$cookie_name = 'Warriors Quests';
$cookie_domain = '';
$cookie_path = '/';
$cookie_secure = 0;

$language = 'en';

define('PUN', 1);

?>

Any suggestions? I'm totally lost.

I didn't see anything on config.php with 'permissions'
