OK, I'm stumped, and have been staring at this for hours.

I'm setting a cookie at /access/login.php with the following code:

setcookie('username', $username, time() + 604800, '/');

When I try to logout, which is located at /access/logout.php (and rewritten to /access/logout), the cookie won't seem to unset. I've tried the following:

setcookie('username', false, time()-3600, '/');

setcookie('username', '', time()-3600, '/');

setcookie('username', '', 1, '/');

I've also tried to directly hit /access/logout.php, but it's not working.

Nothing shows up in the php logs.

Any suggestions? I'm not sure if I'm missing something, or what's going on, but it's been hours of staring at this code and trying to debug.
