Image upload not working in byethost server

Question

I have written code on image upload, but it is not working in byethost server. I created "uploads/products" directory under root location of server, the folder is also writable, but still it is not working. Please help.

I turned on error logging for the application. If I visit "application/logs" directory's log file following error is shown.

ERROR - 2018-03-25 00:47:08 --> 404 Page Not Found: /index

ERROR - 2018-03-25 00:58:24 --> The upload path does not appear to be valid.

Code of my Product Controller.

if(isset($_FILES['productimage']['name'])){
    $filename = $_FILES['productimage']['name']; 
    $config['file_name'] = $filename;
    $config['upload_path'] = realpath(FCPATH.'uploads/products/');
    $config['allowed_types'] = 'jpg|jpeg|png';    
    $config['remove_spaces'] = TRUE;
    $config['encrypt_name'] = TRUE;
    $config['min_width'] = 360;
    $config['min_height'] = 360;
    $config['max_width'] = 360;
    $config['max_height'] = 360;
    $this->upload->initialize($config);
    if($this->upload->do_upload('productimage')){
        $uploadeddata = $this->upload->data();
        $data['image'] = $uploadeddata['file_name'];
    }else{
            $this->session->set_flashdata('error', $this->upload->display_errors());
            $result = array("status"=>false, "message"=>$this->upload->display_errors());
    }

}

Check upload_tmp_dir permissions (permissions for user, that PHP uses). Native file uploading comes in two steps: uploading to tmp dir and moving to whatever you want.

Also be sure you are trying to upload file that meets upload limit.
