Php cookie, header, Cannot display page error

[keyboard]

YYYYYYYYYYYYYYYYEEEEEEEEEEEEEEEEEEEESSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
(I fixed it)

I changed

setcookie("password", "", time() - 3600);

to

setcookie("password", "", time() - 3600, '/');

to make it work throughout the entire directory's and now it works fine?

Thanks for all your help djr33!

Oh, right. If you're doing that in a subdirectory, it will only work there and in contained directories.
Same for subdomains if that's relevant for you. (And HTTPS.)
