How can I use "local.xml" to add back a previously removed block? I am converting the login page to a 2 column layout. Now, I know that there are workarounds in the web by Alan Storm, but I was wondering how do I go it using local.xml without any changes using core Magento.
Once a block is removed, it marks an attribute called "ignored". After that, it doesn't seem to reset the flag and thus future blocks are not rendered.
