Problem: Integrating Erfurt Wiki into WordPress

Hi, I want to integrate ErfurtWiki to WP. I installed latest versions of both: WP (into my root) and ErfurtWiki (into a directory). Both services work fine separately, but I want to combine them (big surprise!:). I have modified index.php to read:
[code]
<?php
define("EWIKI_SCRIPT", "index.php?id=");
include_once("./encyklopedie/ewiki.php");
/* Short and sweet */
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
?>
[/code]
and added
[code]
<?php echo ewiki_page(); ?>
[/code]
to the very bottom of header.php of my theme. Wiki content displays just fine, but no post are displayed. 🙁 Thanks for any hint.
