CodeIgniter 3：“您尚未指定任何允许的文件类型。 您尝试上传的文件类型是不允许的。“

Question

I'm attempting to do a File Upload using the CodeIgniter "upload" library, but everytime I try to upload something I get this error:

"You have not specified any allowed file types. The filetype you are attempting to upload is not allowed."

I've searched and tried many solutions here on StackOverflow but none of them are working, here's my code:

views/screenshots.php

<form method="post" enctype="multipart/form-data" action="{baseurl}/upload/screenshot">
                    <input type="hidden" name="serverid" value="{id}" />
                    <label>Carica uno Screenshot</label>
                    <br />
                    <label class="custom-file" id="customFile" for="screenshot">
                        <input type="file" class="custom-file-input" id="screenshot" name="screenshot" aria-describedby="fileHelp">
                        <span class="custom-file-control form-control-file"></span>
                    </label>
                    <br />
                    <button type="submit" class="btn btn-secondary">Carica file</button>
                </form>

config/upload.php

$config['allowed_types'] = '*';
$config['max_size'] = 1024 * 8;
$config['encrypt_name'] = TRUE;

controllers/upload.php

public function screenshot()
{
    /* Upload library config */
    $config['upload_path'] = './files/screenshots/';
    $this->upload->initialize($config);

    /* Upload and check if it's failed */
    if (!$this->upload->do_upload('screenshot')) {
        $error = array('error' => $this->upload->display_errors());
        echo json_encode($error);
        print_r($this->upload->data());
    } else {
        /* Making an array with all the data of the upload */
        $upload_data = $this->upload->data();

        /* Making an array to pass to the Screenshot_model */
        $screenshot = array(
            'id_server' => $this->input->post('serverid'),
            'id_user' => $this->session->userdata('userid'),
            'image_url' => $upload_data('file_name')
        );

        /* Saving the Screenshot info into the database */
        $this->Screenshot_model->addScreen($screenshot);

        /* Redirect to Server edit */
        redirect('/screenshots/'.$screenshot['id_server']);
    }

}

print_r($this->upload->data()) result

Array ( [file_name] => download.png [file_type] => image/png [file_path] => C:/xampp/htdocs/gameparade/files/screenshots/ [full_path] => C:/xampp/htdocs/gameparade/files/screenshots/download.png [raw_name] => download [orig_name] => [client_name] => download.png [file_ext] => .png [file_size] => 1806 [is_image] => 1 [image_width] => [image_height] => [image_type] => [image_size_str] => )

I'm autoloading the library. My version of CodeIgniter is 3.1.6. I've also tried to use form_open_multipart(); in the view, but nothing changes.

I'm using XAMPP 7.2.0 on Windows 10 (PHP Version 7.2.0).

Replace:

$this->upload->initialize($config);

with:

$this->upload->initialize($config, false);

From the docs (https://www.codeigniter.com/userguide3/libraries/file_uploading.html):

initialize([array $config = array()[, $reset = TRUE]])

Parameters:

$config (array) – Preferences

$reset (bool) – Whether to reset preferences (that are not provided in $config) to their defaults
