[ildefonso99]

Смотрю в лого, там:
[10-Sep-2018 03:38:55 UTC] PHP Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/fishrich/public_html/inc/conf.php:1) in /home/fishrich/public_html/actions/in.php on line 6
[10-Sep-2018 03:38:55 UTC] PHP Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/fishrich/public_html/inc/conf.php:1) in /home/fishrich/public_html/actions/in.php on line 6
Вот отрывок из in.php:
<?php
include('../inc/conf.php');
ini_set('session.use_cookies', 'On');
ini_set('session.use_trans_sid', 'Off');
session_set_cookie_params(604800000, "/", SITE, false, false);
session_start(); - ВОТ ЭТА СТРОКА

Помогите пожалуйста, не понимаю что сделать надо...
