title: Magento, Fatal error, 'Call to ... getAllOptions() on a non-object ... Core\Model\Cache.php'
body: <p>After adding to my frontend/default/[theme]/ folder I hit an error where the site would no longer load. I removed the offending file, but the site still won't load. Enabling PHP error output leads to this message:</p>
  
  <pre><code>Fatal error: Call to a member function getAllOptions() on a non-object in C:\websites\[snip]\htdocs\app\code\core\Mage\Core\Model\Cache.php on line 449
  </code></pre>
  
  <p>I have cleared the cache, and nothing is being created in the var/cache folder when pages are (attempted to be) loaded... Any ideas what else could be cached somewhere?</p>
  
  <p>Also note, this has taken both the frontend and backend offline, so I have no access to the admin system.</p>
  
  <p>This appears to be the same problem mentioned here (<a href="https://stackoverflow.com/questions/8979305/site-down-fatal-error-includes-src-mage-core-model-cache-php-on-line-434">site down - Fatal error: includes/src/Mage_Core_Model_Cache.php on line 434</a>). I don't have the compiler enabled though, so the error is directly in Core/Model/Cache.php. </p>
