==========================

.. include:: /If-you-encounter-this-exception.rst.txt

$className must implement interface `PageLayoutViewDrawItemHookInterface::class`
======================================================================================

- Try deleting all caches
- Older versions: Try deleting all files in :file:`typo3temp/autoload` through
  console.

``rm -rf typo3temp/autoload/*``

Solution TYPO3 8.4.x and higher
===============================

.. note::

   Note that the `PageLayoutView` has changed a lot in newer TYPO3 versions,
   make sure to update your code accordingly.

The way registering the hook has changed in :file:`ext_localconf.php`::

      // Prior TYPO3 8
      // $TYPO3_CONF_VARS['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem'][] = 'EXT:extensionkey/Classes/Hooks/PageLayoutViewDrawItemHook.php:&Vendor\\Extensionkey\\Hooks\\PageLayoutViewDrawItemHook';

   ::

      // TYPO3 8:
      $TYPO3_CONF_VARS['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem'][] = 'Vendor\\Extensionkey\\Hooks\\PageLayoutViewDrawItemHook';
