I want to login vBulletin through my site

[userform3]

Hi,

from a CMS the user should log in to the vb.
The login procedure takes place in CMS.

At vb I got this https://www.vbulletin.com/forum/blog...n-your-website link sent to me by the users.
For the purpose of the login I created a plugin, registered in vb Backen.
The plugin itself is stored in

/var/www/dieseite2_de/html/forum/core/packages/dieseite2/api/dieseite2.php

When opening the forum via the URL www.test.dieseite.de/forum/ I get the following message:

Couldn't read config file config.php.

The error message is generated in the file

/var/www/dieseite2_de/html/forum/includes/vb5/config.php

What am I doing wrong?
Has the plugin been stored in the wrong place?

Anyone have any idea how to solve this?

Hi,

after joining a user did not change my approach.
I have outsourced the login procedure to the CMS and combined it into one function:

PHP Code:

function do_login_vb(){
    
        $vbpath = '/var/www/die_seite2_de/forum';
        define('CSRF_PROTECTION', false);
        require_once($vbpath . '/includes/vb5/autoloader.php');
        vB5_Autoloader::register($vbpath);
        // Script is only executed up to this point!
        vB5_Frontend_Application::init('config.php');
        // Attempting to include the config file, but unfortunately they only issue an error message
        #vB5_Frontend_Application::init('/var/www/die_seite2_de/forum/config.php');
        #vB5_Frontend_Application::init('/var/www/die_seite2_de/forum/core/includes/config.php');
        
        $username = 'xxxxxxx';
        $password = 'xxxxxxx';
        $api = Api_InterfaceAbstract::instance();
        
        $loginInfo = $api->callApi('user', 'login', array($username, $password));        
        // Only one test edition
        echo "<pre>loginInfo: " .print_r( $loginInfo, true ). "</pre><hr>";                
    } 


When you call the forum that is integrated in the CMS, the following message is displayed:

Couldn't read config file config.php.

Anyone any idea how I can fix the message?
Or what is the cause?
Thank you in advance.

Just a guess, but either provide the full path here:

vB5_Frontend_Application::init('config.php');

Or (possibly better), use PHP's chdir() to change the script's virtual environment to the vBulletin installation's expected working directory for the duration of the script (if I'm right, this would mean no further errors of this type).
