Why can't I download from here

zxwitsme

I use fc2 and firefox,but when I want to download a file here,
System prompt:

Warning: Cannot modify header information - headers already sent by (output started at /sfroot/home/groups/linuxfans/htdocs/nuke/header.php:32) in /sfroot/home/groups/linuxfans/htdocs/nuke/modules/Site_Downloads/index.php on line 563

It's so strange.

Anybody can help me?
