this is the warning where i have the header:

Warning: Cannot add header information - headers already sent by (output started at /usr/local/plesk/apache/vhosts/certifyexpress.com/httpdocs/review/admin/disimage.php:11) in /usr/local/plesk/apache/vhosts/certifyexpress.com/httpdocs/review/admin/disimage.php on line 798

make sure you don't have anything at all, including any whitespace or new lines before you send the headers.

Nope. i dont' have any whitespace....no new lines.

what about <html>, included files that print out something themselves?

There's defintely something being output but if you can't locate it then put ob_start() at the top of your page and then ob_end_flush() at the bottom
