title: Can't figure out how to fix codeigniter's sessions not saved issue
body: <p>I'm using php 5.4.17RC1 moved from a server with php 5.3,
  since then codeigniter's session aren't working (or working sometimes..)</p>
  
  <p>I saw that there's a difference between the phpinfo on my old &amp; new server which is:
  Registered save handlers = files user (new server)
  Registered save handlers = files user sqlite</p>
  
  <p>Does anyone have a clue??</p>
  
  <p>Thank you</p>
