在Opencart 1.5.6.4中显示完整的面包屑

Question

我已经安装了一个干净版本的Opencart v1.5.6.4和一个用于v1.5.5.1。现在，当您单击主页上的产品时，面包屑的行为方式之间存在差异。如果我点击主页上的产品，则为1.5.5.1版本的面包屑。是主页＆gt; category-name＆gt;产品名称，但对于版本1.5.6.4，它是主页＆gt;产品名称即可。你知道这个差异来自哪里吗？它是模板或Opencart版本中的东西还是在设置中？提前谢谢。

在类别产品网址上：

  ？

路线=产品/产品＆安培;路径= 18＆安培; PRODUCT_ID = 47

首页产品网址：

  ？

路线=产品/产品＆安培; PRODUCT_ID = 47

when category page to display full breadcrumb with category 
name using " path=18 " get category id 18 to name. 

Full breadcrumb url使用此功能，您可以获得主页产品或其他地方的完整面包屑。
