Re: Making myself nuts over subcategory not showing..HELP!
If the default template is 'acting weird' then it's likely that the previous designer made modifications without using override files. Below is a list of all the primary files for that page - might be better for you to start from scratch by reinstalling fresh copies:
includes/templates/template_default/tpl_index_categories.php
includes/templates/template_default/tpl_modules_category_row.php
includes/modules/category_row.php
includes/modules/pages/index/header_php.php
includes/modules/pages/index/main_template_vars.php
