Is the error from the "PHP Notice: Undefined variable: sessions_rows_affected in /var/www/inc/sessions/model/_hitlist.class.php on line 268"?

Have changed $sessions_rows_affected to $sessions_rows_affected_i. Not entirely sure if that's the right thing to do or not but guess will find out when this task is next executed (24 hours from now)
