Problem uploading PDF Files

[eluser]anthropos9[/eluser]
I've tried every fix I can find for this problem and nothing seems to work. I've tried on both Safari 4 and FF 3.5. I'm on a Mac so IE isn't an option. Does anyone have any other suggestions on how I can get this to work? I really need to be able to upload PDF files. Thanks. Below is my code - maybe some fresh eyes can see a problem.

The file type being listed by $_FILES[$field_name]['type'] is application/pdf with no quotes or commenting out.

Code:

function _pdfUpload(){
        $config['upload_path'] = './images/frontpages/';
        $config['allowed_types'] = 'pdf';
        $config['max_size'] = '1000';
        
        $this->load->library('upload', $config);
        
        $field_name = 'pdf';
        if (!$this->upload->do_upload($field_name)){
            die($_FILES[$field_name]['type']);
        } else {
            $data = $this->upload->data();
            return $data;
        }
    }

In my mimes file this is the line for PDF:

Code:

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