title: Codeigniter Ion Auth configuration
body: <p>I am using Ion Auth for registration, and everything is working fine on local, So when I wanted to move Live server I need email activation for new registrations [I am not using SMTP, there is no email config file in my config folder], So I made changes in ion_auth.php in config file as follows::</p>
  
  <pre><code>$config['email_activation']           = TRUE; 
  $config['manual_activation']          = FALSE; 
  $config['use_ci_email'] = TRUE;
  </code></pre>
  
  <p>as far as I know about this library (I am new to CodeIgniter), that's it. But unfortunately these configurations are not taking effect. When I var dump the following items inside constructor of ion_auth.php library file returns null</p>
  
  <pre><code>$this-&gt;config-&gt;item('use_ci_email','ion_auth') or
  $this-&gt;config-&gt;item('email_activation','ion_auth')
  </code></pre>
  
  <p>And other config items like 'admin_email' has no issues, I can fetch the value. So, what is wrong with my config file, I am using very basic file provided by the library repo. </p>
  
  <p>When I set the values, inside the constructor of library file as below, it works.</p>
  
  <pre><code>$this-&gt;config-&gt;set_item('use_ci_email', TRUE);
  $this-&gt;config-&gt;set_item('email_activation', TRUE);
  </code></pre>
  
  <p>Is there anything wrong I am doing to get this weird behavior.</p>
