In Magento version 1.6.1.0, I noticed when previewing a transactional email it displayed in html only. Obviously this isnt right so I come up with this little fix.
Copy: app/code/core/Mage/Adminhtml/Block/System/Email/Template/preview.php
To: app/code/local/Mage/Adminhtml/Block/System/Email/Template/preview.php
Change (Line:49):
$template->setTemplateText(
$this->escapeHtml($template->getTemplateText())
);
To:
//$template->setTemplateText(
//$this->escapeHtml($template->getTemplateText())
//);
Upload and it should display properly.
