title: CodeIgniter Install Problem
body: <p>I'm having a problem getting CodeIgniter to work on my shared hosting account.  The URL is <a href="http://test.tallgreentree.com" rel="nofollow noreferrer">http://test.tallgreentree.com</a>.  It's not giving me a .php error, but it is displaying a 404 page for everything I type into the address bar.</p>
  
  <p>Here's the beginning of my config.php file.</p>
  
  <pre><code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
  
  /*
  |--------------------------------------------------------------------------
  | Base Site URL
  |--------------------------------------------------------------------------
  |
  | URL to your CodeIgniter root. Typically this will be your base URL,
  | WITH a trailing slash:
  |
  |   http://example.com/
  |
  */
  $config['base_url'] = "http://test.tallgreentree.com/";
  
  /*
  |--------------------------------------------------------------------------
  | Index File
  |--------------------------------------------------------------------------
  |
  | Typically this will be your index.php file, unless you've renamed it to
  | something else. If you are using mod_rewrite to remove the page set this
  | variable so that it is blank.
  |
  */
  $config['index_page'] = "index.php";
  
  /*

  | URI PROTOCOL
  |--------------------------------------------------------------------------
  |
  | This item determines which server global should be used to retrieve the
  | URI string.  The default setting of "AUTO" works for most servers.
  | If your links do not seem to work, try one of the other delicious flavors:
  |
  | 'AUTO'            Default - auto detects
  | 'PATH_INFO'       Uses the PATH_INFO
  | 'QUERY_STRING'    Uses the QUERY_STRING
  | 'REQUEST_URI'     Uses the REQUEST_URI
  | 'ORIG_PATH_INFO'  Uses the ORIG_PATH_INFO
  |
  */
  $config['uri_protocol'] = "AUTO";
  </code></pre>
  
  <p>Are there known issues when using CodeIgniter with subdomains? What could be causing this?  I've tried multiple configurations, but nothing seems to be working for me.  What server settings should I check with my hosting provider?</p>
  
  <p>Thank you all for your time and assistance.</p>
