title: Login & Session not working on localhost using codeigniter & Ion_Auth
body: <p>I have a live site which works fine and can be logged into no problems. I have a local copy of that site but for some reason the session isn't working. If i login, i can tell that the login has worked as it tries to redirect to the success page and i can see that a new session gets started.</p>
  
  <p>But, the system doesn't recognise me as being logged in.</p>
  
  <p>I've changed the cookie_domain config variable, changed session_ip and session_user_agent matching variables but nothing seems to work.</p>
  
  <p>Also, i increased the size of the fields that hold session/userdata data in the db to longtext to make sure nothing was being chopped off.</p>
  
  <p>Is there anything i've missed, anything that i've forgotten?</p>
