title: Magento custom module adminhtml/base/default
body: <p>My custom module is generating this error on the system log everytime I try to view the indexController.</p>
  
  <pre><code>2012-01-25T17:23:08+00:00 CRIT (2): Not valid template file:adminhtml/base/default/template/page/2columns-right.phtml
  </code></pre>
  
  <p>I've been fishing through my module code for hours, just can't seem to find anything wrong. What could cause this? The base/default folder doesn't even exist under adminhtml.</p>
