I'm getting the following error: Warning: Cannot modify header information headers already sent by (output started at ...includes/database.mysqli.inc:128) in ...includes/bootstrap.inc on line 636,637,638,639

here are the lines:

header("Expires: Sun, 19 Nov 1978 05:00:00 GMT");
header("Last-Modified: ". gmdate("D, d M Y H:i:s") ." GMT");
header("Cache-Control: store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", FALSE);

anyone know how to get around this problem?

did you check your database?
did someone screw up the install files?
someone mess with the core files?
some touch something outside of the "sites" folder?
is your computer plugged in? is it switched on?

everything worked fine...and then one day BAM! I didn't touch anything...

make sure there's no trailing whitespace in the file, or if you have template.php...make sure there's no whitespace after ?>
