Logout error, can not find connection class

I have the following logout code:

<?php
    require_once 'session.php';
    require_once 'User.php';

    $user_logout = new User();
    if($user_logout->is_loggedin()!="")
    {
        $user_logout->redirect('./index.php');
    }
    if(isset($_GET['logout']) && $_GET['logout']=="true")
    {
        $user_logout->doLogout();
        $user_logout->redirect('../../login.php');
    }
?>

Where it makes the request for class User.php that holds all the user's functions. Here is the Logout () function:

<?php

require_once './connect/Connect.php';

class User
{   

    private $conn;

    public function __construct()
    {
        $database = new Database();
        $db = $database->dbConnection();
        $this->conn = $db;      
    }

    public function runQuery($sql)
    {
        $stmt = $this->conn->prepare($sql);
        return $stmt;
    }

When I click the logout button it displays the following error:

  

Warning: require_once (./ connect / Connect.php): failed to open stream:   No such file or directory in   C: \ wamp \ www \ onsistem \ connect \ User \ User.php on line 3

Another application that has the same code is working, it's pretty much the same, does anyone have any idea what the error might be?
