500 Error

[JUG]

Ok, so I had issues with Error 500. Maybe this helps to someone:

I got Error 500 every time I tryed to access any page other than index.php. Error occured when I copyed login.php from users to usersc or when I copyed index.php and renamed it. Only index.php was working correctly.

Solution: in every page you create you must have some php code

<?php
require_once 'users/init.php';
require_once $abs_us_root.$us_url_root.'users/includes/header.php';
require_once $abs_us_root.$us_url_root.'users/includes/navigation.php';
?>

change code above with the one below

<?php
require_once $_SERVER['DOCUMENT_ROOT'].'/users/init.php';
require_once $abs_us_root.$us_url_root.'users/includes/header.php';
require_once $abs_us_root.$us_url_root.'users/includes/navigation.php';
?>

Note the / before users/init.php!
