Your error 404 page has an error (or rather two, probably the same one twice):

Warning: Invalid argument supplied for foreach() in /home/lojjic/css3pie.com/wp/wp-content/themes/pie-wp-theme/header/header-default.php on line 56
Warning: Invalid argument supplied for foreach() in /home/lojjic/css3pie.com/wp/wp-content/themes/pie-wp-theme/footer/footer-default.php on line 39

Thanks for letting me know!
