Session does not work on live server in Codeigniter
Sometime we face a problem with session while moving site from localhost to the live server. So if you get error message something like that: A PHP Error was encountered Severity: Warning Message: mkdir(): Permission denied Filename: drivers/Session_files_driver.php Line Number: 117 SOLUTION: Just add below code to your config.php, This would be really helpful to you. $config [ 'sess_save_path' ] = sys_get_temp_dir();
