Add to cart button missing on shop/archive page

Subject: Add to cart button missing on shop/archive page (mobile & desktop) — only quantity input shows

Hello,

I’m running WoodMart 8.5.7 on WordPress 7.1, WooCommerce 11.1.0, PHP 8.3.33, on ferrotiendaec.com.

Issue: On the shop/category archive pages, product cards show only the quantity stepper (-/1/+) — there is no visible “Add to cart” / “Select options” button. This happens on Android, iPhone (Safari), and desktop Chrome alike. Increasing the quantity does NOT add the item to the cart.

What I’ve already tried:

Cleared all caches (LiteSpeed + host-level) and tested in private/incognito windows on multiple devices — identical result.
Checked the browser console — no relevant JS errors.
Raised max_input_vars from 5000 to 10000 (was below WoodMart’s own recommended minimum) and re-saved theme settings — no change.
Under Theme Settings → Shop → Product archive → Products loop, toggled “Quantity input on product” OFF — this caused the button to render as a malformed, textless shape instead of fixing it (site-wide). Reverted back ON.
Found and deactivated a plugin called “Electro Extensions,” whose own description states it’s built exclusively for a different theme (“Electro”) and is not compatible with any other theme.
Confirmed Elementor is installed but inactive (active builder is WPBakery).
Found what looks like the same issue reported on your own forum: https://xtemos.com/forums/topic/woodmart-theme-add-to-cart-button-and-quantity-missing-in-mobile-view/
My catalog has 34,000+ simple products, so a clear, always-visible “Add to cart” button on the shop/archive grid is critical for conversions.

Could you help identify the remaining cause and the correct configuration for the button to display reliably across all devices?

Thank you,
