php - Codeigniter: The filetype you are attempting to upload is not allowed

Question

I'm using CI latest version. Got error while uploading a JPG files. I use the code from here https://www.codeigniter.com/userguide3/libraries/file_uploading.html and a little bit from Multiple files upload in Codeigniter

The Controller:

$config = array(
'upload_path'   => 'path to upload',
'allowed_types' => 'jpg|gif|png|jpeg',
'overwrite'     => 0,
'max_size'      => 1024,                       
);
$this->load->library('upload', $config);
$this->upload->initialize($config); // Make sure it has been initialized

if (!$this->upload->do_upload('gambar1')){
    $error = array('error' => $this->upload->display_errors());
    return $error;
}else{ echo 'success'; }

The View:

<?php echo form_open(base_url().'report/send', 'method="post" enctype="multipart/form-data"', $hidden);?>
<input type="file" class="hidden" name="gambar1"></form>

When I'm trying to upload JPG files, it gives me The filetype you are attempting to upload is not allowed. Any idea?

SOLUTION: I've try to upload it to server. But it still gives me the same error. Then i found this: Codeigniter : The filetype you are attempting to upload is not allowed. Yesterday it was fine "The most recent time I have had this is when I upgraded my core Codeiginter version from 2.x to 3.x. I updated the contents of the system directory, but not application/config. I didn't spot the fact that the application/config/mimes.php file is slightly different - the newer version returns an array whereas the old one included it as a var. The fix was to copy in the newer version of mimes.php"
