title: Ion Auth Codeigniter - Default User/Password Not recognised
body: <p>I'm new to Codeigniter and Ion Auth. Installed everything OK and set up the ION Auth DB tables. Go to BASE_URL/index.php/auth and I got an error about using encryption. So, I edited that in config by adding a simple string for now.</p>
  
  <p>So, now I can see the login form - good! But when I use the default user and password, I'm getting incorrect password validation...which suggests there is something wrong. </p>
  
  <p>Any ideas why this would be failing? I'm using admin@admin.com and password, as indicated on the Ion Auth pages <a href="http://benedmunds.com/ion_auth/" rel="nofollow">http://benedmunds.com/ion_auth/</a>. </p>
  
  <p>Thanks in advance.   </p>
