I have magento installed in a subdirectory. www.domain.com/subdir/magento

This site worked perfectly at one point. I changed nothing, until my client said he could

Find app/code/core/Mage/Core/Model/Session/Abstract/Varien.php. in your Magento install folder. Comment out the lines (see below) 80 to 83. The line number may vary.

    // set session cookie params
    session_set_cookie_params(
        $this->getCookie()->getLifetime(),
        $this->getCookie()->getPath()//,
        //dependes which versin of mage you are using, you may comment these as well
        //$this->getCookie()->getDomain(),
        //$this->getCookie()->isSecure(),
        //$this->getCookie()->getHttponly()
    );

This is caching issue. Which recently Magento community confirmed that is sorted but it is not. :)

Just clear your cache and do this steps it should work anyway.

Comment this lines also

//        if (!$cookieParams['httponly']) {
//            unset($cookieParams['httponly']);
//            if (!$cookieParams['secure']) {
//                unset($cookieParams['secure']);
//                if (!$cookieParams['domain']) {
//                    unset($cookieParams['domain']);
//                }
//            }
//        }
//
//        if (isset($cookieParams['domain'])) {
//            $cookieParams['domain'] = $cookie->getDomain();
//        }

• Make sure you have cookies enabled in your browser, try a number of different browsers including Safari or Opera. Chrome will give some problems and you need to remember to clear you cache in Chrome after making changes!

• Make sure you file permissions are set to EVERYONE - FULL CONTROL for Windows and 777 for your Mac/Linux environment If all that still doesn’t work you can try this: (I do not recommend this solution for a production version of Magento, but for you local test enviroment this will work.)

• Check the version of php you are using. If you are using recent Magento try to find which version of PHP and extensions requires.
