HTACCESS setEnv doesn't work for all servers

If the server is running Apache then mod_env must be enabled for setEnv to work. I have run into cases where mod_env is not enabled in shared hosting setups.

The fix that has worked for me is to change the define in index.php to this.

PHP Code:

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'production');
