We have some problems when we include static cms blocks into the template with our Magento 18.104.22.168
We include the cms block this way:
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('cms-block-name')->toHtml() ?>
The problem is that the Doctype and HTML-Structure is included everytime with the cms block. We don't know how and can't find a way to fix it.
