CodeIgniter giving 500 Internal Error just on 1 page

Question

I uploaded my site on live. All website is working perfectly but 1 page is showing me 500 Internal Server Error.

Can you tell me why?

This is my controller.

defined('BASEPATH') OR exit('No direct script access allowed');

class Game extends CI_Controller {

I set the environment to production and I see a blank page. No errors. — Ali Zia, Oct 21 '16 at 11:10
set `TRUE` for `db_debug` in database.php file and chk the DB errors — devpro, Oct 21 '16 at 11:11
The page is working perfectly on localhost. Just not on live. — Ali Zia, Oct 21 '16 at 11:16
Sounds like a BOM character, probably at the very start of the document. Make absolutely sure that ` — DFriend, Oct 21 '16 at 11:21
one last test, if you are using CI3 than your class name must start from capital letter Game.php — devpro, Oct 21 '16 at 11:28
Yes I checked it. The error is in this line. 'image', 'id' => 'image']); ?> — Ali Zia, Oct 21 '16 at 11:30
Yes i tried and it worked. Thankyou you all. I was looking in the wrong direction. — Ali Zia, Oct 21 '16 at 11:38

You are using short array tag in your code for production.

<?php echo form_upload(['name' => 'image', 'id' => 'image']); ?>

You just need to use like simply:

<?php echo form_upload(array('name' => 'image', 'id' => 'image')); ?>

Your PHP version is not allowed you to use php short tag array.

Update:

Adding comment of @Simba: You need to upgrade your php version urgently -- short array format has been around since PHP 5.4. If your php doesn't support it, then it means you're on a very old and unsupported version. You need to upgrade to avoid security issues. Being able to use modern php features like short array format will be a bonus, but the security worries of running an old version should be more important.
