Hello Friends, Magento is an open-source ecommerce web application.It was created by Varien, building on components of the Zend Framework. Magento is well architected and well designed ecommerce platform. So after hearding so many advantages of Magento and after getting one project in Magento I got one chance to work with Magento. So I downloaded it and install it in my local. After installing Magento in local I tried to login into admin but I was not able to login in Magento admin. First I thought that I entered wrong username/password but it was not giving any error like ‘Invalid Username and Password.’, So it means there is some problem while loggin into admin of Magento. I searched about his problem and found solutions for this which are explaining below.

1. If you are using latest version of Magento : If you are using latest version 1.4.1.1 then you have to follow these steps to log in into admin.
– Open magento\app\code\core\Mage\Core\Model\Session\Abstract\Varien.php file and go to line number 96.

– You will see piece of code like shown below :

if (isset($cookieParams['domain'])) {
$cookieParams['domain'] = $cookie->getDomain();
}

– Just replace it with code given below :
if (isset($cookieParams['domain']) || 1 == 1) {
$cookieParams['domain'] = $cookie->getDomain();
}

– Save file.

– Now try to log in into admin. Voila!! Now it is working.

2. If you are using older version than 1.4.1.1 version : If you are using older version then you have to follow these steps to log in into admin.

– Open magento\app\code\core\Mage\Core\Model\Session\Abstract\Varien.php file.

– Find code given below in this file :

session_set_cookie_params(
$this->getCookie()->getLifetime(),
$this->getCookie()->getPath()
$this->getCookie()->getDomain(),
$this->getCookie()->isSecure(),
$this->getCookie()->getHttponly()


– Replace this code with code given below :

session_set_cookie_params(
$this->getCookie()->getLifetime(),
$this->getCookie()->getPath()
//$this->getCookie()->getDomain(),
//$this->getCookie()->isSecure(),
//$this->getCookie()->getHttponly()

– Save File.

– Now try to log in into admin. Voila!! Now it is working.

So these are the two ways for old version and new version by which we can solve problem of can’t login into admin of Magento. Let me know if you have any other solution or any other suggestions for Magento can’t login into admin problem.
