Are you running the browser on the same system that you have php and web server installed on? If so, and you are accessing yourlogin page, how are you doing it? Are you accessing it by localhost or an IP address? If you are using localhost and are then later getting redirected etc your cookies are likely getting set under localhost, but once you get to a page to delet them the page is being referred to by IP or name and therefor can not find the appropriate cookie.
