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[\'uploa         


        

Answer 1

Instead of

$this->load->library('upload',$config);

Try this

$this->load->library('upload'); $this->upload->initialize($config);

This works for me
