Codeigniter does not load Upload Library - php

Question

We are trying to upload some files with Codeigniter, and for some reason this piece of code is not working.
Loading the library in "autoload" works perfectly, still, not the best solution, for the obvious reasons.
Curiously, is working in another website that I have.
<?php
// set options
$config['upload_path'] = FCPATH.$path;
$config['allowed_types'] = 'png|jpeg|jpg|gif';
$config['max_size'] = 2048;
$config['encrypt_name'] = TRUE;
$config['overwrite'] = TRUE;
$config['max_width'] = 0;
$config['max_height'] = 0;
// check if folder exists
if( ! is_dir($config['upload_path']))
#mkdir($config['upload_path'], 0755, true);
//load upload library
$this->load->library('upload', $config);
//check success of upload
if( ! $this->upload->do_upload($name))
return $this->upload->display_errors();
else
{
// do upload
}
?>
Here is the error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: xxx::$upload
Filename: core/xxx.php
Line Number: 424
Fatal error: Call to a member function do_upload() on null

First make sure $path is correct var dump($path) and check receiving it.
Second you did not have any {} in if part of do_upload and around the is directory
public function do_upload() {
$config['upload_path'] = FCPATH . 'uploads/';
$config['allowed_types'] = 'png|jpeg|jpg';
$config['max_size'] = 2048;
$config['encrypt_name'] = TRUE;
$config['max_size'] = '30000'; // Added Max Size
$config['overwrite'] = TRUE;
$config['max_width'] = 0;
$config['max_height'] = 0;
//load upload library
$this->load->library('upload', $config);
$this->upload->initialize($config);
// check if folder exists
if( ! is_dir($config['upload_path'])) {
#mkdir($config['upload_path'], 0755, true);
}
//check success of upload
$name = "userfile"; // Field name
if( ! $this->upload->do_upload($name)) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
} else {
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
Make sure on view use echo form_open_multipart('controller/do_upload')
