I just notice the directory is only showing 4 subcategories per category.
You can click on any of the top categories and see each has well more than 4 subcategories.
I think the logic failure is in tiki-directory_browse.tpl
It should loop to make another row of subcategories until it runs out of subcategories.
- It's not doing this.
I'm too ignorant at this time to the smarty templating system to see the error.
(Thanks in advance...)
