Make sure that when you enter: require_once( ‘../wp-blog-header.php’);, it’s absolute path. For example: /home/username/archas/ram/wordpress/

To find out what your absolute path is:

1) make a file and call it path.php

2) add this code into the path.php: <?php $p = getcwd(); echo $p; ?>

3) upload it to your wordpress directory and access it http://www.cs.elomza.pl/archas/ram/wordpress/path.php, that will output your path.
