Magento Frontend Login Submit Fails and Clears Fields

Magento Enterprise 1.x

Problem:
Logging in to the Magento frontend customer login page (/customer/account/login/) fails. The form submits, but the page simply reloads and clears email/password fields. This is common when copying a site from one domain to another e.g. production domain to development domain.

Solution:
Check config value web/cookie/cookie_domain in core_config_data table. Update to match current domain or set to NULL (as needed).

Magento Hack Fix to Remove Persistent '(Not Name?)' Link in Header

Problem: Magento Enterprise persistent shopping cart shows the following text in the page header: '(Not Name?)'

Solution:
Magento creates a dynamic header block in code and an unset or remove layout instruction doesn’t remove the block.  In your local.xml, overwrite the block with an empty core/template block with the same name.  i.e.

<!-- Hack fix to remove persistent '(Not Name?)' link top of page. -->
<!-- unsetChild and remove actions do not work. -->
<!-- Html generated here: app/code/core/Mage/Persistent/Block/Header/Additional.php -->
<!-- Block created dynamically here: app/code/core/Mage/Persistent/Model/Observer.php see header.additional -->
<block type="core/template" name="header.additional"/>
