# Mini-Cart Popups Not Working After Theme or WooCommerce Update

If add to cart pop-ups stop working in your mini-cart or side cart after a theme or WooCommerce update, update [Popups for WooCommerce: Add to Cart, Checkout & More](https://wpfactory.com/item/popup-notices-for-woocommerce/), clear all caches, then check the Pro **AJAX add to cart notice** settings at **WPFactory > Popups**. Set a wrapper **Selector** if **Smart find** no longer finds one.

## Common symptoms

- Adding a product shows the default notice, or nothing, instead of the pop-up.
- The pop-up is missing only in the side-cart or mini-cart flow, not on the normal cart or checkout.

## Why a mini-cart breaks the pop-up

When a product is added by AJAX (from a shop page, a quick view or a side cart), WooCommerce does not print an add to cart notice. The Pro **AJAX add to cart notice** option fills that gap: after WooCommerce's standard AJAX add to cart, it inserts a success notice into a notices wrapper, and the pop-up reads it from there. Two things can stop this after an update:

- **No wrapper is found.** **Notices wrapper - Smart find** (on by default) looks for an empty WooCommerce container or an existing notice on the page. A new theme layout may have neither.
- **The side cart uses its own AJAX.** The option listens to WooCommerce's standard add to cart event. A side-cart plugin that adds products its own way may never trigger it.

## AJAX add to cart notice options (Pro)

| Setting | Option ID | Default |
| --- | --- | --- |
| AJAX add to cart notice | `ttt_pnwc_opt_ajax_add_to_cart_notice_enable` | No |
| Notices wrapper - Smart find | `ttt_pnwc_opt_ajax_add_to_cart_notice_wrapper_smart` | Yes |
| Notices wrapper - Action hook | `ttt_pnwc_opt_ajax_add_to_cart_notice_wrapper_hook` | Empty |
| Notices wrapper - Selector | `ttt_pnwc_opt_ajax_add_to_cart_notice_wrapper_selector` | Empty |

The Action hook and Selector are only used when **Smart find** is off. For a selector, enter a CSS selector of an element that exists on your shop pages, for example the main content container; the wrapper is added at the start of it.

## Fix it, step by step

1. **Update both** WooCommerce and Popup Notices to their latest versions; recent releases include checkout and mini-cart compatibility fixes.
2. **Clear caches** (server, CDN, cache plugin), especially with aggressive caching or JS/CSS minification.
3. **Enable the AJAX add to cart notice (Pro):** mini-carts add products via AJAX, so this option and its wrapper settings (**Smart find**, **Action hook**, or **Selector**) are what place the pop-up. See [Show an add to cart pop-up on shop and archive pages](https://wpfactory.com/docs/woocommerce-ajax-add-to-cart-popup/).
4. **Test with a default theme** such as Storefront and the default mini-cart to see whether the theme is overriding it.
5. **If it works on the default theme** but not yours, the theme's custom mini-cart needs a matching wrapper hook or selector; set one in the AJAX add to cart notice options.

## Prevent it next time

- Re-test the mini-cart flow after each theme or WooCommerce update.
- If you rely on the side-cart experience, include it in your update checklist.

## FAQ

### Why does the pop-up work on the product page but not from the shop page?

The product page reloads and WooCommerce prints a normal notice, which the free plugin turns into a pop-up. Shop page adds use AJAX with no notice, so they need the Pro AJAX add to cart notice option.

### Which wrapper option should I try first?

Keep Smart find on. If nothing appears, turn it off and enter a Selector for a container that exists on your shop and category pages.

### Could caching cause this?

Yes. Minified or combined JavaScript from an old cache can load the previous plugin script. Clear every cache after updating.
