Common issue after installing Magento SUPEE 6788

After installing Magento SUPEE 6788 patch, some custom blocks may disappear from the front page as Magento has added new restrictions in the blockDirective method with the security patch.

You need to find out if the type of block to be displayed is allowed in the permission_block database table. A new code in the Mage_Core_Model_Email_Template_Filter class will check to see if it exists in the table. To resolve issues with custom blocks that are not listed in permission_block and consequently will not be displayed, you need to follow the steps below:

  • Determine your custom blocks to be used in cms {{block}} directive

  • Go to System/Permissions/Blocks, add your block type if allowed.

Now, you can open the file: app/code/core/Mage/Core/Model/Email/Template/Filter.php file in a text editor, look for public function blockDirective somewhere around the 169th line, and then, add the following commands:

Mage::log($blockParameters[‘type’], null, ‘blocks_used.log’, true);

Afterwards, you are able to log all blocks that Magento is checking:

// ...

/* Mage_Core_Model_Email_Template_Filter */

public function blockDirective($construction)
  $skipParams = array('type', 'id', 'output');
  $blockParameters = $this->_getIncludeParameters($construction[2]);
  $layout = Mage::app()->getLayout();

  if (isset($blockParameters['type'])) {

     Mage::log($blockParameters['type'], null, 'blocks_used.log', true);

     if ($this->_permissionBlock->isTypeAllowed($blockParameters['type'])) {
        $type = $blockParameters['type'];
        $block = $layout->createBlock($type, null, $blockParameters);
   } elseif (isset($blockParameters['id'])) {
        $block = $layout->createBlock('cms/block');
        if ($block) {

// ...

Finally, you just need to flip through all the pages on your Magento store while the block types will be automatically logged in the var/log directory. Please copy and add them to the allowed block types.

Similarly, variables can also be affected by the SUPEE 6788 Magento security patch. So you can add variables by going to System > Permissions > Variables.

Plugins that use custom variables should be updated. Please check in the following example:

if (version_compare(Mage::getVersion(), '', '>=')) {

    $installer = $this;
    $connection = $installer->getConnection();


            array('block_name' => 'core/template', 'is_allowed' => 1),
            array('block_name' => 'catalog/product_new', 'is_allowed' => 1),
