Pada tutorial kali ini, kami akan membahas seputar error yang terjadi pada fungsi session_start() dalam file session.php. Berikut ini contoh pada Ecommerce Abantecart yang mengalami masalah tidak dapat menemukan file atau folder untuk menyimpan session data, sehingga kita perlu memverifikasi pengaturan pada session.save_path.

Solusi:
Debian tidak menggunakan default garbage collector untuk sessions. Dengan demikian, it sets session.gc_probability to zero and it runs a cron job to clean up old session data in the default directory. As a result, if your site sets a custom location with session_save_path() you also need to set a value for session.gc_probability, e.g.:
<?php
session_save_path('/home/example.com/sessions');
ini_set('session.gc_probability', 1);
?>
Otherwise, old files in '/home/example.com/sessions' will never get removed!
Tambahkan kode berikut pada line 77 dan 78 (sebelum session_start() diekseskusi. Untuk melihat keseluruhan file session.php dapat mengakses Code GitHub
