I am just a newbie to the magento. I have installed magento on my localhost. After all the setup when I used the admin page to login I can\'t able to login in chrome browser
This is my simple solution that helped me in the same situation. Try it for 60 seconds of your time.
In Google Chrome, in Developer Tools (right-click on any page element and select Inspect Element), go to the Resources -> Cookies tab. Delete the extra cookie for your original domain. Or set your base url domain to something else, or change the port.
