A sql-issue related to the breadcrumb trail

[Qim]

Hi, I have modified may shop quite a bit now. Still have some issues to resolve.

 

One of these is wrt breadcrumb trail. Please look at my shop and click on a subcategory. Visit My Website

On the main page you will se the name of that subcat. The same subcat is in the breadcrumb trail

which of course is redundant, and needs to be eliminated. I have changed classes/breadcrumb.php

to get the subcat on the main page, which I want. See Code below.

 

Q: What and how, do I change the breadcrumb trail, so that the redundant info is excluded?

 

Many thanks in advance, and happy holidays / Qim
