Because IE engineers CANNOT READ a technical document to save their
lives, you MUST supply a "path" if you supply a "time":
setcookie("cookiename", $values, time() + $timevalue, "/");
You also don't tell use what $timevalue is, so that could be something
very wrong... :-)

Unless you have register_globals set to "ON" (bad!) then $values will
only have meaning in the setcookie script...

You should NOT NOT NOT NOT NOT be storing a username *or* password in

What *is* in your cookies?
var_dump($_COOKIES);
Perhaps putting '|' in there is not a valid character?
You could base64 encode it or ...

It would be some chunk of the Netscape Cookie spec.
Google for "Netscape Cookie spec" and read that. It's only a page.
