<action method="setColumnCount"><columns>4</columns></action>                    

                <action method="setItemLimit"><type>related</type><limit>4</limit></action>

Answer 1

你关闭了你的块:

<block ... />

我想这会导致错误.

试试这段代码:

<block type="catalog/product_list_related" name="catalog.product.related" as="product_additional_data" after="product.info.upsell" template="catalog/product/list/related.phtml">
  <action method="setColumnCount">
    <columns>4</columns>
  </action>                    
  <action method="setItemLimit">
    <type>related</type>
    <limit>4</limit>
  </action>
</block>
