After installing CodeIgniter please download the bootstrap template here I use Bootstrap Zero. Just follow the steps:
$autoload[‘helper’] = array();In the array add the URL helper
$autoload['helper'] = array('url');
► Open the welcome_message.php file located on Codeigniter/application/views. File welcome_message.php is the initial view after installing CodeIgniter. Then remove the existing tags except the PHP script at the top of the file
<?php defined(‘BASEPATH’) OR exit(‘No direct script access allowed’);?>open one of the views of the template we downloaded in this case the author chose login.html which will be the initial view when run.
