Hola, como estan? Escribo este post para solicitar ayuda con el siguiente error luego de instalar parches de seguridad.

Cuando intento editar Bloques me aparece el siguiente error:

Fatal error: Undefined class constant 'XML_NODE_ALLOWED_MEDIA_EXT_SWF' in /home/skinfact/public_html/app/code/core/Mage/Cms/Helper/Data.php on line 70

Desde ya muchas gracias a quien me pueda ayudar!

Hi @marianocac0be9 

If I am not wrong you have applied SUPEE-11155 patch on your site.

Check in your Magento Code, if you have app\code\core\Mage\Cms\Helper\Data.php file  (Mage_Cms_Helper_Data class) overridden in local or community code pool.

You do not have following code line 

const XML_NODE_ALLOWED_MEDIA_EXT_SWF    = 'adminhtml/cms/browser/extensions/media_allowed/swf';

after 

const XML_NODE_ALLOWED_STREAM_WRAPPERS  = 'global/cms/allowed_stream_wrappers';

code line.

After adding the mentioned code line you will not get an error.
