My website has lost its pageination?

Did you use a shortcode to make this page? Shortcodes don’t have pagination. The page does not have “archive” in its body class, so it doesn’t look like a product category page.

If you make a category called “apparel” and so tag all relevant products, you should be able to find your apparel products with pagination and drop-down sorter at this url:
