When payment fields disappear during checkout, most WooCommerce store owners immediately suspect a payment gateway outage or plugin conflict. In reality, cookie consent platforms can sometimes block critical scripts that payment processors require to function properly. This can prevent customers from entering payment information and lead to abandoned carts and lost revenue.
This guide explains how a WooCommerce checkout issue was traced to CookieYes and how adjusting cookie consent behavior restored payment processing.
Issue Background
An eCommerce website began receiving reports that customers could not complete purchases. Credit card fields failed to appear during checkout, and alternative payment methods such as Cash App were also unavailable.
The issue affected multiple browsers and devices, indicating a site-wide problem rather than a user-specific error. Because payment processing was impacted directly, the problem required immediate attention.
Diagnosis
Investigation focused on WooCommerce checkout functionality, payment gateway integrations, and recently updated plugins.
- WooCommerce Square payment fields were not loading.
- Cash App payment options were unavailable.
- Checkout pages loaded normally aside from payment inputs.
- CookieYes was actively managing script consent.
- Required payment scripts were categorized as non-essential and blocked.
Additional testing revealed a script loading order issue introduced through recent WooCommerce updates. Together, these factors prevented Square payment assets from initializing correctly during checkout.
Resolution Steps
1. Identify blocked payment scripts
Review browser developer tools and plugin settings to determine whether payment-related JavaScript files are being blocked.
2. Verify CookieYes categorization
Confirm payment gateway scripts are not assigned to optional consent categories.
3. Implement a temporary server-side exception
Create logic that allows WooCommerce Square scripts to load on checkout and cart pages regardless of consent categorization.
4. Correct script loading order
Resolve dependency issues that may prevent payment scripts from initializing correctly.
5. Mark payment scripts as Necessary
Update CookieYes settings so essential checkout functionality is never blocked.
6. Test all payment methods
Verify credit card payments, Cash App functionality, gift card fields, and checkout workflows across multiple devices.
Final Outcome
After adjusting CookieYes behavior and correcting the script loading sequence, all WooCommerce payment fields loaded properly. Credit card processing, Cash App payments, and other checkout components functioned normally, allowing customers to complete purchases without interruption.
Organizations using WooCommerce, Square, CookieYes, Cash App, and consent management platforms should carefully review how cookie banners interact with payment gateways to avoid blocking critical checkout functionality.
