MyBB Community Forums

Since I'm not getting any views or help in my support thread I'll try it here.

$forumdir = "/"; // change this if you want the script to work outside your forums..

//end editing


define("IN_MYBB", 1);

if(substr($_SERVER['SCRIPT_NAME'],0,1) == "/")
{
    define('THIS_SCRIPT', substr($_SERVER['SCRIPT_NAME'],1));

    define('THIS_SCRIPT', $_SERVER['SCRIPT_NAME']);

$current_dir = getcwd();

//change working directory to allow board includes to work
$forumdirslash = $forumdir."/";
$change_dir = "./";

if(!@chdir($forumdir) && !empty($forumdir))

    if(@is_dir($forumdir))
    {
        $change_dir = $forumdir;
    }
    else
    {
        die("\$forumdir is invalid!");
    }

output_page($chat); 
}

I have MyBB installed under <domain>/forum/
But no matter what I do it always says $forumdir invalid

I tried:
$forumdir = "/forum/";
$forumdir = "/forum";
$forumdir = "http://www.dedeno.net/forum/";
$forumdir = "/users/dutchharbor/public_html/forum/";

But none of them work !
I'm really missing something vital here,

One thread is enough.
