php - facing error as soon as I load session library in my codeigniter 3.0.4 controller -


i have seen , checked other stackoverflow questions , common answer problem

make sure there's no whitespace before <?php tag

even after browsing other blogs , articles regarding issue, still facing same error. if remove load of session, works normal.

my error:

a php error encountered  severity: warning  message: mkdir() [function.mkdir]: no such file or directory  filename: drivers/session_files_driver.php  line number: 117  backtrace:  file: /home/content/97/8248497/html/dvjtest/application/controllers/home.php line: 9 function: library  file: /home/content/97/8248497/html/dvjtest/index.php line: 292 function: require_once  php error encountered  severity: warning  message: cannot modify header information - headers sent (output started @ /home/content/97/8248497/html/dvjtest/system/core/exceptions.php:272)  filename: core/common.php  line number: 568  backtrace:  uncaught exception encountered  type: exception  message: session: configured save path '' not directory, doesn't exist or cannot created.  filename: /home/content/97/8248497/html/dvjtest/system/libraries/session/drivers/session_files_driver.php  line number: 119  backtrace:  file: /home/content/97/8248497/html/dvjtest/application/controllers/home.php line: 9 function: library  file: /home/content/97/8248497/html/dvjtest/index.php line: 292 function: require_once

my controller:

<?php defined('basepath') or exit('no direct script access allowed');  class home extends ci_controller {      public function __construct()     {         parent::__construct();         $this->load->library('session');         $this->load->helper('url');         $this->load->helper('cookie');     }       public function index()     {         $this->load->view('header');         $this->load->view('welcome_message');         $this->load->view('footer');     } }  ?>

session library trying write disk happens involved mkdir() well. need either make path writeable or change session data directory else writeable.

check "sess_save_path" in configs. more documentation on session configs: https://www.codeigniter.com/user_guide/libraries/sessions.html#session-preferences
