custom 404 and routing problems

(This post was last modified: 04-13-2016, 05:31 PM by discotom. Edit Reason: clarification )

I use CodeIgniter.

I route certain urls to different files based on the structure of url using the routes.php file. Everything has been working fine.

However, a few months ago, i thought i would add a custom 404 page. I did and things appeared to be working fine.

HOWEVER, i have just realised that every page on my site (except the home page) gives a server response http status 404 error and yet displays to the human user the correct page. why is it setting a 404 status and not a 200 status??

I have no idea how that's happening but it's obviously a nightmare as i am now not indexed from all search engine listings!!! The only thing i can think of is that i did something when setting the custom 404 page which meant that every page regardless of whether found or not has a 404 status. incidentally, if i try to navigate to a page that doesn't exist, i get my Custom 404 error page. Domain is http://citylightstours.com

My routes.php file is:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
| -------------------------------------------------------------------------
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|   example.com/class/method/id/
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
| Please see the user guide for complete details:
|   http://codeigniter.com/user_guide/general/routing.html
| -------------------------------------------------------------------------
| -------------------------------------------------------------------------
| There area two reserved routes:
|   $route['default_controller'] = 'welcome';
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|   $route['404_override'] = 'errors/page_missing';
| This route will tell the Router what URI segments to use if those provided
| in the URL cannot be matched to a valid route.

$route['default_controller'] = "content";
$route['en/(:num)/(:any)'] = "content/en/$1";
$route['de/(:num)/(:any)'] = "content/de/$1";
$route['es/(:num)/(:any)'] = "content/es/$1";
$route['it/(:num)/(:any)'] = "content/it/$1";
$route['ar/(:num)/(:any)'] = "content/ar/$1";
$route['404_override'] = '';

/* End of file routes.php */
/* Location: ./application/config/routes.php */

My .htaccess file is:

Can anyone help please?

Can anyone help - is there any other code i should post??

Have you found a solution yet? Because I visited your website, tried a few links and everything sends a 200 statuscode, instead I go for some random site, that doesn't exist. If this error still exists (maybe in development) I think we need some extract of your controller and maybe the error class to see how you implemented the errorpage.
