Cant setup external login

[DaSpamer]

Hello, I'm trying to set up external login but getting fatal errors that I can't seem to fix.

My script is

PHP Code:

ini_set('display_errors',1);
ini_set('display_startup_errors',1);
define("VB_PATH",realpath(dirname(__FILE__)));
// Start login script
define('CSRF_PROTECTION', false);
require_once(VB_PATH . '/includes/vb5/autoloader.php');
vB5_Autoloader::register(VB_PATH);
vB5_Frontend_Application::init('config.php');
$api = Api_InterfaceAbstract::instance(); 


The error I'm getting is

Fatal error: Class 'vB_Request_WebApi' not found in /home/USER/public_html/_vb5/includes/api/interface/collapsed.php on line 38

Fatal error: Class 'vB_Shutdown' not found in /home/USER/public_html/_vb5/core/vb/vb.php on line 502

Couldn't find anything related to my issue anywhere on the internet, hope someone could help me out.

Did you upload all the files from the package? Based from the error message, it looks like /home/USER/public_html/_vb5/core/vb/request/webapi.php and /home/USER/public_html/_vb5/core/vb/shutdown.php are missing.

Yes I did upload all files, I'm using vb5.2.3, didn't modify anything, uploaded from a fresh download.
Both files exist, both classes are inside those files, but it seems that somewhat they're not being used, and I have no idea what's the problem, reuploading doesnt seem solve it.

Where is that external script located? Could you do var_dump(VB_PATH)?

[DaSpamer]

the extrenal script is located at the base dir same dir where core.
var dump output is

string(31) "/home/user/public_html/_vb5"

which is the forum base.

Issue was that I defined VB_PATH and is messed up something inside.
wish they had documentary so I could actually know what I can and cannot do.

So you got it?

I use this code if the external login code is inside the forum directory.

<?php
define('CSRF_PROTECTION', false);
require_once(__DIR__ . '/includes/vb5/autoloader.php');
vB5_Autoloader::register(__DIR__);
vB5_Frontend_Application::init('config.php');
echo $vbulletin->userinfo['username'];
