# Popups Disappear or Cart/Coupon Inputs Vanish (Flicker Issue Fix)

If pop-ups from Popups for WooCommerce: Add to Cart, Checkout & More flash and vanish, or the coupon field disappears on the cart or checkout, clear or raise Auto-close time (Pro) in the General section at WPFactory > Popups, check Prevent closing if clicking outside, clear all caches, and test with a default theme and other plugins disabled.

### Common symptoms

- The pop-up shows for a second, then closes before it can be read.
- After removing a coupon, the coupon field disappears from the cart or checkout.

### Fix it, step by step

1. **Check auto-close (Pro):** go to **WPFactory > Popups** (also reachable at **WooCommerce > Settings > Pop-up Notices**) and clear or raise **Auto-close time** in the General section so pop-ups stay long enough to read.
2. **Review the outside-click setting:** if you rely on clicking away to dismiss, make sure **Prevent closing if clicking outside** is set the way you expect.
3. **Rule out conflicts:** temporarily switch to a default theme and disable other plugins, especially caching, optimization, and checkout-customizing plugins, then retest.
4. **Clear caches:** clear page cache, CDN, and any JS/CSS minification so a stale copy of the plugin script `pnwc-frontend.min.js` is not being served.
5. **Check AJAX handling:** if the coupon field is removed by another script after an AJAX update, isolate that script during the default-theme test.

**Tip:** for checkout and coupon pop-ups, leaving auto-close off gives the customer time to read and act, which is better UX.

### Still stuck?

If the field disappearance persists after these steps, contact us with your theme and active plugin list on the [Popup Notices support forum](https://wpfactory.com/support/item/popup-notices-for-woocommerce/) so we can reproduce it.
