I am trying to display the sub-categories from a certain category in magento in the left side bar. I found a few solutions saying I have to change the code in app\design\frontend\base\default\template\catalog avigation\left.phtm but I only have top.phtml and verticalcollapse.phtml. However the code that displays the left column is this getChildHtml('left') ?>. This is in app/design/frontend/default/forest_classyshop/template/page/2collumn-left.phtml.
My question is where can I find the code "left" that should be in the left.phtml that's missing?
