Here's what worked for me in 4.0.x:
In
skin1/customer/categories.tpl:
1. Find the following line:
2. Insert the following code AFTER the line you just found:
Code:
{section name=sub_num loop=$allcategories}
{if $allcategories[sub_num].parentid == $categories[cat_num].categoryid}
<FONT class="CategoriesList">-
{$allcategories[sub_num].category}</font>
{/if}
{/section}
3. Save and refresh.
One,
