Why doesn't it work???

[harry1951]

? need some help...
After reading this thread http://www.vbulletin.com/forum/showthread.php?t=81549 this is what I need.
I made a testpage http://www.jestaatnietalleen.nl/test1.php

It is an empty page with this in it:

<?php
chdir('./forum');
require('./forum/forumdisplay.php?f=4');
chdir('../') ;
?>

I also tried require_once but with same errors...

I also made an other testpage http://www.jestaatnietalleen.nl/test2.php

The script there is:

<?php
require('http://www.jestaatnietalleen.nl/forum/forumdisplay.php?f=4');
?>

I get output there but then all other vBulletin files are expected in the rootpath..

What do I wrong???
