Warning: Trying to access array offset on null in /wp-content/plugins/woocommerce/includes/class-wc-form-handler.php on line 567 Warning: Trying to access array offset on null in /wp-content/plugins/woocommerce/includes/class-wc-form-handler.php on line 571
This warning may cause concern for both shop owners and customers. Below, we explain what this message means, why it appears, and how to fix or completely remove the payment method management option from the customer account.
What does this error mean?
This PHP error message says that there is an attempt to read data from a non-existent array (null). To put it simply:
WooCommerce is trying to get payment data (e.g., from a card or payment gate), but this data does not exist or was not correctly passed.
Common causes:
1. ❌ No active payment gateway that supports storing methods (e.g., Stripe, Braintree).
2. 🧩 Payment method plugin error or incompatibility.
3. 🧼 Deleting the payment method from the gateway, but not from the user account.
4. 🔧 WooCommerce version incompatible with the chosen payment gateway.
How to fix this issue?
1. **Install or properly configure a payment gateway**
Only some payment gateways support storing and managing methods (e.g., Stripe, Braintree, PayPal Vault). Ensure that:
* A supported gateway is installed.
* It’s properly configured.
* The API for saving methods is available.
2. **Update your WooCommerce shop and payment method plugins**
The error may result from incompatibility – check if all plugins are updated to the latest versions.
3. **Remove or hide the “Payment Methods” section from the customer account**
If you don’t use gateways that allow payment data storage, you can:
* Hide this section using a filter in your theme:
“`php
add_filter( ‘woocommerce_account_menu_items’, ‘usun_metody_platnosci_z_konta’ );
function usun_metody_platnosci_z_konta( $items ) {
unset( $items[‘payment-methods’] );
return $items;
}
“`
* Or redirect users from this section elsewhere.
Additional diagnosis
If the issue persists, try:
1. Enabling WooCommerce debugging → WooCommerce → Settings → Advanced → Error logs.
2. Checking which plugin is responsible for the problem.
3. Using WordPress debug mode (WP_DEBUG in wp-config.php).
