Customer Can't log in
Do you have a custom template and did it work in 1.7? In 1.8.1 form_keys were added, so please check your custom template for this line:
<?php echo $this->getBlockHtml('formkey'); ?>
if it is missing, add it as in
/app/design/frontend/base/default/template/persistent/customer/form/login.phtml
And check all other forms after the update:

http://www.blueclawsearch.co.uk/blog/2013/12/12/fix-customer-cannot-login-to-magento-1-8-1/ this is a solution for the problem
Here's what the above link has to say:
Go to
template/customer/form/login.phtml
andtemplate/persistent/customer/form/login.phtml
and under<ul class="form-list">
Add the following code in the login form
<input type="hidden" name="form_key" value="<?php echo Mage::getSingleton('core/session')->getFormKey(); ?>" />
If you are using the login form in different templates then you use add the form_key
to the other parts as well.
