Magento 1.9 login loop , no redirection to dashboard
<p>i have a Magento 1.9.1 stack, it was working fine but now when tried to login to the magento admin dash, It doens't offer an error like "Incorrect username or password", it just reloads the login page. And when I refresh the page i get the dashboard . </p>

<p>Any help with this is greatly appreciated.!</p>
