Sessions

I now can't log into the admin or the seller or buyer areas?

The config has


$config['sess_driver'] = 'files';
$config['sess_save_path'] = FCPATH.'ci_sessions';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;


When I look in  ci_sessions there is a session in there for when I log in but after that it has created a new session every second or more

It is only writing something to ci_sessions once you have tried to log in. Non of the old sessions are getting deleted either if that helps.

Any Ideas please?
