I have already tested the issue by deactivating all plugins and switching to the default theme, but the problem still persists. Because of this issue, users are unable to create orders.

I found the following errors in the error logs:2026-08-14T02:35:03+00:00 Debug #5948 - [New Request] POST / 2026-08-14T02:35:03+00:00 Error #5948 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:35:03+00:00 Error #5948 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:13+00:00 Debug #1858 - [New Request] POST / 2026-08-14T02:38:13+00:00 Error #1858 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:13+00:00 Error #1858 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:16+00:00 Debug #6651 - [New Request] POST / 2026-08-14T02:38:16+00:00 Error #6651 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:16+00:00 Error #6651 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:50+00:00 Debug #3872 - [New Request] POST / 2026-08-14T02:38:50+00:00 Error #3872 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:50+00:00 Error #3872 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:54+00:00 Debug #4755 - [New Request] POST / 2026-08-14T02:38:54+00:00 Error #4755 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:38:54+00:00 Error #4755 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:40:22+00:00 Debug #7541 - [New Request] POST / 2026-08-14T02:40:22+00:00 Error #7541 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:40:22+00:00 Error #7541 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:40:26+00:00 Debug #1153 - [New Request] POST / 2026-08-14T02:40:26+00:00 Error #1153 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:40:26+00:00 Error #1153 - Cart simulation failed: Error adding products to cart. 2026-08-14T02:41:58+00:00 Debug #6962 - [New Request] GET /product/kafka/

I also tested the site in incognito mode, and the following error appears in the browser console on the product page:ppcp-button-js-butto…js?ver=1786700918:1 Uncaught (in promise) {name: '', message: 'Error adding products to cart.', code: 0, details: Array(0)} (anonymous)@ppcp-button-js-butto…js?ver=1786700918:1 Promise.then(anonymous)@ppcp-button-js-butto…js?ver=1786700918:1 value@ppcp-button-js-butto…js?ver=1786700918:1 value@ppcp-button-js-butto…js?ver=1786700918:1 i@ppcp-button-js-butto…js?ver=1786700918:1 (anonymous)@ppcp-button-js-butto…js?ver=1786700918:1 value@ppcp-button-js-butto…js?ver=1786700918:1 value@ppcp-button-js-butto…js?ver=1786700918:1 value@ppcp-button-js-butto…js?ver=1786700918:1 (anonymous)@ppcp-button-js-butto…js?ver=1786700918:1 (anonymous)@ppcp-button-js-butto…js?ver=1786700918:1 Promise.then vt@ppcp-button-js-butto…js?ver=1786700918:1 (anonymous)@ppcp-button-js-butto…js?ver=1786700918:1 T@tabba-85-midi-length…ed-poly-duchesse/:3 await in Tt@tabba-85-midi-length…ed-poly-duchesse/:3 await in trun@tabba-85-midi-length…ed-poly-duchesse/:3 (anonymous)@tabba-85-midi-length…ed-poly-duchesse/:3 (anonymous)@tabba-85-midi-length…ed-poly-duchesse/:3

When I go to the checkout page, I get another JavaScript error:ppcp-axo-js-boot.js?ver=4.1.2:1 Uncaught TypeError: Cannot read properties of null (reading 'insertAdjacentHTML') at e.value (ppcp-axo-js-boot.js?ver=4.1.2:1:49098) at e.value (ppcp-axo-js-boot.js?ver=4.1.2:1:48303) at HTMLInputElement.<anonymous> (ppcp-axo-js-boot.js?ver=4.1.2:1:43090) at HTMLDocument.dispatch (jquery.min.js?ver=3.7.1:2:40035) at v.handle (jquery.min.js?ver=3.7.1:2:38006) at Object.trigger (jquery.min.js?ver=3.7.1:2:70124) at HTMLInputElement.<anonymous> (jquery.min.js?ver=3.7.1:2:70701) at ce.each (jquery.min.js?ver=3.7.1:2:3129) at ce.fn.init.each (jquery.min.js?ver=3.7.1:2:1594) at ce.fn.init.trigger (jquery.min.js?ver=3.7.1:2:70701)

The errors appear to be related to the PayPal Checkout/PayPal Complete Payments scripts (ppcp-button and ppcp-axo).

Could you please investigate this issue and determine why the cart simulation is failing and why the PayPal scripts are throwing these JavaScript errors?

I have also recorded a video showing the issue here:

This issue is currently preventing customers from completing their orders, so it needs to be resolved as soon as possible.
