Magento - 无效的块类型

Question

Whenever I place an order using Buckaroo's Payment Guarantee method I get a message saying: Your payment was not successful. Please try again or choose another payment method.

The following stack trace code then gets added to the exception.log file:

   2014-03-07T14:10:26+00:00 ERR (3): 
    exception 'Mage_Core_Exception' with message 'Invalid blocktype: ' in /app/Mage.php:594
    Stack trace:

It says invalid blocktype: and doesn't appear to display a name.

Don't suppose it has anything to do with this bit of code which creates a block in the form.phtml of the payment method?

<?php echo $this->getLayout()->createBlock('core/template')->setTemplate('buckaroo3extended/paymentguarantee/termsAndConditions.phtml')->toHtml();?>

Answer 1

most probably there is a block declared in your layout file without a type.
Something like this:

<block name="cart_sidebar" ...>...</block>

and it should be

<block type="checkout/cart_sidebar" name="cart_sidebar">...</block>

or it should be

<reference name="cart_sidebar">...</reference>

My money is on the second one. So look in your layout files for cart_sidebar.
