Wordpress templates not working
===

I've been trying to make this work for a few hours now and I give up, I need help. I installed theCartPress plugin and it created tcp_product_category taxonomy for tcp_product post type. I created a page with custom template to list all the product categories ([http://palivonas.lt/test/islosaitis/catalogue][1]).

I can use single-tcp_product.php, but taxonomy-tcp_product_category.php doesn't work. I tried removing tcp_ (it's rewritten like that), tried everything from template hierarchy. I installed "Reaveal template" plugin and when I visit http://palivonas.lt/test/islosaitis/product_category/spinteles/ it shows "archive.php". I tried changing code, nothing changes there. I emptied archive.php, category.php, index.php, page.php and nothing changed in that link, still shows "Category Archives: spintelės" title and list of products. Any ideas?

Don't mind any layout issues, I'm just trying to make it work, then design.
