Is it the includes?

[zzz]

I have a subdomain with SSL: secure.domain.net
which is actually appears in a form of sub-directory when viewed via FTP environment, i.e. /secure.domain.net

I'm trying to hit a file, login.php which is currently residing on the root level via link from index.php, which is also on the root level.

Here's how the code looks:

index.php

<?
include("include/config.php");
$pagetitle = "test";
include("include/header.php");
?>

<a href="<? echo $https ?>/login.php">login</a>

[/COLOR]

include/config.php

<?
$https = "https://secure.domain.net";
?>

I need to be in a secure environment when I het to login.php file. Currently I'm getting there but with the following errors:

Warning: main() [function.main]: open_basedir restriction in effect. File(/usr/local/lib/php/include/config.php) is not within the allowed path(s): (/var/www/domains/domain.net) in /var/www/domains/domain.net/login.php on line 2

Warning: main(include/config.php) [function.main]: failed to create stream: Operation not permitted in /var/www/domains/domain.net/login.php on line 2

Warning: main() [function.main]: Failed opening 'include/config.php' for inclusion (include_path='.:/usr/local/lib/php') in /var/www/domains/domain.net/login.php on line 2

What am I doing wrong?

<? 
include("include/config.php"); 
$pagetitle = "test"; 
include("include/header.php"); 
?> 

<a href="<? echo $https ?>/login.php">login</a> 

k.. whats your exact dir. structure?

root folder contains:
login.php
index.php
etc.
correct?

and inside the includes folder:
header.php
config.php

the value of https should be https domain hence..
-> [url]https://secure.domain.net/login.php[/url] should work... so

try this -> <a href="<? print $https; ?>/login.php">login</a> 

try just printing out $https
make sure it's printing right..
etc.
