CodeIgniter Upload class PDF filetype not allowed

Question

Works locally but on the two servers I've tried the same error message is shown. Using Codeigniter 2.1.3

private function upload_file(){
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'jpg|png|jpeg|gif|pdf';
    $config['max_width']  = '0';
    $config['max_height']  = '0';
    $config['encrypt_name']  = true;
    $this->load->library('upload', $config);
    var_dump($_FILES);
    if ( ! $this->upload->do_upload()){
        $error = array('error' => $this->upload->display_errors());
        var_dump($error);
        die();
        return $error;
    } else {
        $data = array('upload_data' => $this->upload->data());
        var_dump($data);
        die();
        return $data;
    }
}

While doing the var_dump($_FILES); it shows the correct information array(1) { ["userfile"]=> array(5) { ["name"]=> string(8) "0002.pdf" ["type"]=> string(14) "aplication/pdf" ["tmp_name"]=> string(27) "C:\Windows\Temp\php9454.tmp" ["error"]=> int(0) ["size"]=> int(29295) } }

var_dump($error) giving off array(1) { ["error"]=> string(64) " The filetype you are attempting to upload is not allowed. " }

Tested with both a png and jpg and these works marvelously.

The correct mime-types are in the config file config/mimes.php

 'pdf'  =>  array('application/pdf', 'application/x-download'),

Edit: If it means anything, the local server is a MAC and the two remotes are windows.

So even though the code is all correct the error is actually on PHP itself. There's a spelling mistake in there mime-types. When var_dump($_FILES) it spitting out ["type"]=> string(14) "aplication/pdf" Note that "application" is spelt wrong.

Checked on workmates machine and his correct, so might be an issue with php >5.3.5
