从magento从1.7升级到1.9.1后，客户无法登录

Question

I recently upgraded magento from 1.7 to 1.9.1. All the features seems to be working including added extensions.

When a customer is trying to login, it redirects it back to the login page with error.

Invalid login or password.

I tried adding formkey code to the login form but no success in logging in. I used both the formkey codes that I found posted by some users, which they say it works for lots of other users

    <?php echo $this->getBlockHtml('formkey'); ?>

and

    <input type="hidden" name="form_key" value="<?php echo Mage::getSingleton('core/session')->getFormKey(); ?>" />

Is this because password is stored in different format in Magento 1.9.1 than in Magento 1.7?

Anyone has any other solutions?

Answer 1

Solution: In my case, it was the encryption method. Previously, the Magento setup I had, used to have sha256 encryption rather than md5. FORMKEY should have worked I guess if I did not had this encryption. I just had to change

app/code/local/Mage/Core/Model/Encryption.php

public function hash($data) {return md5($data);}

to

public function hash($data) {return hash('sha256', $data);}
