Unable to run codeigniter project in wamp virtual host.

What is the URL when you receive that message? To me, the following doesn't look right:

Code:

saseco.dev/<?=site_url('login/user_login');?>

The site_url() method should be providing the saseco.dev/ portion for you, so I would expect this to produce an invalid URL.

I generally keep each of my host configurations in a separate file. Additionally, the Directory configuration is usually inside the VirtualHost configuration, unless a directory is shared between multiple hosts. You may also need to make sure your opening and closing tags match in your server config file(s).
