I have found the solution right here :

you have to write your incude like this :
<?php include(ABSPATH . “../myfile.php”); ?>
ABSPATH is the root of your wordpress blog
Hy,
I have also the same problem,
Like jmwebguy, I want to includes php files witch are located in the parent directory of the Blog
I’ve tried <?php include (get_bloginfo(‘url’) . ‘/myfile.php’); ?> first and <?php include (‘../../../../../myfile.php’); ?> next
the problem is the same.
the only include, seams to work, is when header.php and the other file are in the same directory.
Any idea ?
