go to index.php change template_css.php to template_css.css it looks like your server does not support ob_start (\"ob_gzhandler\"
; and I alos get additional 404 error so it looks like the file is not there at all.template_css.php. if you server does not support it make change to mootools.v1.1.compressed.php also . Rename it to mootools.v1.1.compressed.js. There are instructions about this in index.php. Let me knwo if this works. We renamed these files for faster site load . So test fisrt if the files are there
