After installing magento can't log in to admin panel

23 April 2009 32 Comments

Problem Description
While installing magento on xampp version 2.5 you have provided admin username and password. After installation finished you no longer login with your admin account. In fact in the “Log in to Admin Panel” window whenever you provide wrong password/username combination it displays “Invalid Username or Password.” But whenever you provide correct password it does not show anything. Though a new url like
is displayed on the address bar.
Everytime you do this you can”t log in to admin panel.

Cause of the problem
The problem occurs because magneto could not store cookies. We run it as localhost and localhost is not true domain but to store cookies we need a domain. That”s why login stops without saying any word.

Solution of the problem
Way 1:
In different forums I saw they mentioned connecting as http://localhost/magento/index.php/admin will fail but if you connect as it will work. But in my case IP address in the URL did not work too.
I made it be Aanbevolen spellen online casino Aanbiedingen Bankzaken Help FAQ Als u nog nooit videopoker hebt gespeld, wordt di teen ware traktatie. work into whenever I changed my browser. Suppose I installed magento using google chrome browser and I open admin url into my firefox window and it worked. Though in the firefox the url http://localhost/magento/index.php/admin did not work, but url worked fine.

Way 2:
-Go to app/code/core/Mage/Core/Model/Session/Abstract/Varien.php file within your magento directory.

-Find the code,


-Replace above code by,


-Save it and try to login to your magento admin panel.
It would work. :)

    the only solution that works
    if u only comment the lines instead of replacing text take a good look at commas

  • Joguy said:

    The server is windows server 2003 and Xampp.

    Thanks you.

    Solution 2 is right. There’s only one piece of code block to temporarily disable in one of Magento’s Core files. Found this blog that tells the same remarkable solution. http://markuzweb.blogspot.com/2009/08/cant-login-to-magento-admin-panel-after.html

  • Dawod said:

    Error log record number: 1663895226

    can any one help me

  • kajal said:

    I worked all the solutions provided for this error
    I would suggest if none of the codes works for u than try this one
    it worked for me..
    None of the above..

    In fact, in version you can comment only the line #100 ( call_user_func_array(’session_set_cookie_params’, $cookieParams); ) and it will work

  • admin (author) said:

    Note that when you comment 3 lines, you also need to removed character , on the line ‘path’ => $cookie->getPath(),
    This is really must be $cookieParams = array(
    ‘lifetime’ => $cookie->getLifetime(),
    ‘path’ => $cookie->getPath()
    //‘domain’ => $cookie->getConfigDomain(),
    //’secure’ => $cookie->isSecure(),
    //‘httponly’ => $cookie->getHttponly()
    Hope that it works for you

  • Dawod said:

    Thanx to all my admin Panel is working now

  • ThinkClothingArt said:

    Thanks to Kajal above, commenting line 100 worked, that was an easy fix that only took a few hours to figure out. :) Thanks Varien for the great local install instructions on windows :)
    I will try Richard’s too which seems quite comprehensive, but for a quick fix Kajal worked.
    Now to figure out this pesky index.php url rewriting issue now that I can log in. Boy talk about out of the box turn key. Maybe they shoudl package up a developer local install instead of having to work all this out via forums.
    Cheers Guys.

  • jason said:

    @kajal was abt to give up then i saw ur post thankx a million , commenting out line #100 worked for me too ,

  • Vo Tan Tai said:

    I think you have to comment this this line

    //call_user_func_array(\’session_set_cookie_params\’, $cookieParams);

  • Jaso said:

    Hi there,

    I am using this simple procedure under Windows7:
    1. install XAMPP and enable \"iconv\"

    2. edit the file \"hosts\" to this: localhost.com

    3. copy the magento files to the directory: C:\\xampp\\htdcs\\magento\\

    4. start the Apache and MySQL

    5. Go to the address: http://localhost.com/magento

    6. Follow the installation wizard.

    7. Now You will be able login to the administration.
