# Payment Methods by Product & Country: Advanced Troubleshooting

## Advanced troubleshooting

For advanced troubleshooting of [Payment Methods by Product & Country for WooCommerce](https://wpfactory.com/item/payment-gateways-per-product-for-woocommerce/), deactivate other plugins and switch to a default theme to find conflicts. If gateways are not filtered at all, change Add filter in the General tab to On "wp_loaded" action or In constructor. Also check the WP_DEBUG log and the browser console for errors.

### Rule out a plugin or theme conflict

1. Temporarily deactivate your other plugins, then retest checkout.
2. If the problem clears, reactivate them one at a time to find the one responsible.
3. Switch to a default theme (for example Storefront) to rule out theme JavaScript on the checkout page.

### Try the "Add filter" timing option

If gateways are not being filtered at all, another plugin may be registering payment gateways later than expected. In the **General** tab, change **Add filter** (`alg_wc_pgpp_advanced_add_hook`) from the default *On "init" action* to *On "wp_loaded" action* or *In constructor*, save, and retest.

### Check for errors

- Enable `WP_DEBUG` and review the server error log for PHP notices.
- Open the browser console (F12) on the checkout page and look for JavaScript errors that could stop the payment list from rendering.

### Confirm the gateway is available to begin with

The plugin only reorders or removes gateways that WooCommerce already offers. If a gateway is disabled in **WooCommerce > Settings > Payments**, or hidden by another payment-rules plugin, this plugin cannot bring it back.
