Site doesn't work with WWW at the start of the address

Question

We're using EE and I'm also using the Focus Lab Multi Environment Config file on one of our sites and for some reason our site won't work with WWW at the start of the address.

I have confirmed with the hosting provider that everything is correct from their end, but am confused as to where to move from here.

Is there something in the config file that should be modified to make this work again?

Very new to the Focus Lab Config file.

Answer 1

In your Focus Lab Config config.env.php file, you might need to make sure that both www and non www are specified in the switch statement.

switch ($_SERVER['HTTP_HOST']) {
  case 'website.com' :
  case 'www.website.com' :
    define('ENV', 'prod');
    define('ENV_FULL', 'Production');
    define('ENV_DEBUG', FALSE);
  break;

  ...
}

But saying that, you should really only be using one or the other. Being able to access the site using www and non-www will lead to duplicate content on Google. Not good.

Your htaccess needs to have something like this to force the removal of www.

<IfModule mod_rewrite.c>
  RewriteEngine On 
  RewriteBase /  
  RewriteCond %{HTTP_HOST} ^www\.website\.com$ [NC]
  RewriteRule ^(.*)$ http://website.com/$1 [R=301,L]
</IfModule>

There are many different ways to do it and you can find plenty of resources on how to do it.
Here's one on how to force www.
