How to configure a copy of Codeigniter website on a subdomain?

I want to create a testing environment for my working Codeigniter (version 3.1.9) website.
It should be an exact replica of my original website, where I can modify the code and test changes before uploading them to the real website.

I thought I'd do it using a subdomain on my main domain.

I set the subdomain (test.mydoaim.com) through cPanel, and copied all the code files to the relevant directory.

Now, when I go to test.mydomain.com, or to test.mydomain.com/controller_name, it all works well, but when I try any inner links (such as test.mydomain.com/controller_name/anything), I get nothing on Firefox, or this error message on Chrome:

This page isn’t working
www.test.mydomain.com is currently unable to handle this request.

I'm guessing this is an htaccess issue? or a routing issue?
Any pointers on how to make this work would be highly appreciated!

My config/routes.php file is quite simple:

PHP Code:

$route['default_controller'] = 'website';
$route['404_override'] = 'student/four_o_four';
$route['translate_uri_dashes'] = FALSE;
$route['demo'] = 'student/demo'; 


And this is my htacces file:

Code:

RewriteOptions inherit
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

# for non www urls, add www and force https:
RewriteCond %{HTTP_HOST}(.*) !^www\. [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R,L]

Hi,
imho, first thing to check, if you set your subdomain as test.domain.com, try to access... test.domain.com without the www which means: comment those two lines
<code>
RewriteCond %{HTTP_HOST}(.*) !^www\. [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R,L]
</code>
in your htaccess file with an #

second thing i would suggest if this subdomain is a test one, but you may already have done this, create a dedicated db for the subdomain else whatever you change in the db will appear on the production domain too...

hope it helps
have a nice day

Have you set $config['base_url'] to reflect the subdomain, e.g.

PHP Code:

$config['base_url'] = 'https://www.test.mydomain.com'; 


Have you set $config['base_url'] to reflect the subdomain, e.g.

PHP Code:

$config['base_url'] = 'https://www.test.mydomain.com'; 


My base_url seems to be configured OK, since I am able to access  test.mydomain.com, or test.mydomain.com/controller_name.
Its only the inner pages, such as test.mydomain.com/controller_name/anything that cause an error.

This is how my base_url is configured, under config/config.php:

PHP Code:

$protocol = is_https() ? "https://" : "http://";
$host = isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : "";

if(is_cli()){
  $config['base_url'] = '';
}

elseif(stristr($host, "localhost") !== FALSE || (stristr($host, '192.168.') !== FALSE) || (stristr($host, '10.0.2.2') !== FALSE)){
  $config['base_url'] = $protocol . $host . "/pi/";
}

else{
    $allowed_hosts = ['mydomain.tld', 'www.mydomain.tld','anotherdomain.tld','www.test.mydomain.tld'];

    $config['base_url'] = in_array($host, $allowed_hosts) ? $protocol.$host."/" : "we-do-not-recognise-this-host.com";
}

Hi,

I tried removing the www, and I narrowed my htaccess file to just:

Code:

[php]RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L][/php]

But the results are the same  

And yes, I did set up a duplicate db for testing purposes. But that's a good pointer. I t would be a shame to mess up the real db!
