For some reason, my subcategories are not showing up on my category pages. Subcategories are showing up in the sidebar, but when you click on the top-level category, you get the category name with no links to any subcategories. However, products are listed on sub-subcategory pages, and the product page shows up just fine. Basically, the site looks like this:

--> Category Page: nothing

--> --> Sub Category Page: nothing

--> --> --> Sub Sub Category Page: list of products

--> --> --> --> Product Page: product info

I checked using the classic template, and the problem is still apparent. I replaced the "display grid of available subcategories" code in tpl_index_categories from a clean backup just in case, and it did nothing. I've also tried the opposite of removing subcategories from category pages (replacing clean code where it instructs to remove it),and played around with my admin settings, but I'm getting nowhere. Any ideas? TIA!
