vBulletin 5.5 Login problem

[celestora]

Plugin doesn't seem to login users after authorization. I couldn't figure out what the problem is exactly, but probably something seems to destroy the session before callback.php performs a redirect. There is a workaround to stop execution and perform redirect just before end of block (somwhere around line 198):

$result = vB_User::processNewLogin(array(
    'userid' => $userid
));

// Redirect
if (!empty($arguments['origin']))
{
    // Security check
    if (parse_url($arguments['origin'], PHP_URL_HOST) == parse_url($vbulletin->options['frontendurl'], PHP_URL_HOST))
    {
        $redirect_url = $arguments['origin'];
    }
}

# workaround
setcookie("sessionhash", $result["sessionhash"], time()+60*60*24*14, "/", NULL, true, true);
exec_header_redirect($redirect_url);
die;
