Magento 1.8 – Fix Memcache and Sessions Not Working

magento-1.8memcachedsessions

I used memcache for sessions but can not login to both of frontend and backend in mg1810

before this, I did use redis for sessions and now want to use memcache instead of redis

Also did FLUSHALL in redis-cli, memcache service is running and local.xml set to …

<config>
<global>

    <session_save><![CDATA[memcache]]></session_save>
    <session_save_path><![CDATA[tcp://127.0.0.1:11211?persistent=1&weight=2&timeout=10&retry_interval=10]]></session_save_path>

</global>
</config>

Magento uses the memcached php extension to communicate with Memcache, but won't warn you if you don't have it.

Magento – Problem with users and sessions on Magento frontend

Even if this sounds like it's too broad and does not have a version specified, I will take a shot in the dark and assume that your version 1.8.1 and you are using a theme for an older version.
A lot has changed on 1.8.1 and the themes for 1.7 (even 1.8.0) are not compatible anymore.
if you take a look here in the loginPostAction you will see this code:

if (!$this->_validateFormKey()) {
    $this->_redirect('*/*/');
    return;
}

This is new. It validates the form key for additional security. If you don't send a form key you get redirected to the login page without any errors showing.
For test purposes comment the lines I mentioned. If it works then ... bingo....that's your problem.
Uncomment the lines again and make your login form 1.8.1 compatible by adding this code inside the <form> tag in your login template.

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

If my shot in the dark was a miss, and you don't use 1.8.1 tell me and I will delete the answer.

Check if you have the php memcache module installed and enabled (on Debian php5-memcache).
