first make sure that it is a correct path:
/homepages/26/d67453580/htdocs/shop/
if it is then make sure u have it right in your admin/includes/configure.php file.
define('DIR_FS_DOCUMENT_ROOT', '
/homepages/26/d67453580/htdocs/shop/'); // where the pages are located on the server
define('DIR_WS_ADMIN', '/admin/'); // absolute path required
define('DIR_FS_ADMIN', '/homepages/26/d67453580/htdocs/shop/admin/'); // absolute pate required
define('DIR_WS_CATALOG', '/'); // absolute path required
define('DIR_FS_CATALOG', '/homepages/26/d67453580/htdocs/shop/'); // absolute path required
then in easypopulate.php
$tempdir = "temp/";
$tempdir2 = "temp/";
i hope that helps...
