Sessions - Not Working

@iD30

If
$this->CI->load->diver('session');
is still mysteriously needed, there are two more probable causes I can guess:

- Maybe the source you are using for upgrading is an old development snapshot CI 3.0-dev, not the final 3.0.0 release. For being sure, in your server check with
echo CI_VERSION;
what actually is returned.

- (Low probability) Presence of code execution accelerator like apc or another one, then it should be reset.

Thanks for you reply ivantcholakov

The framework download was direct from http://www.codeigniter.com/

Your Low probability - As far as I am aware there isn't any accelerator, but I will double check to make sure - anything is possible.
