Woocommerce Issue with Elementor 4.3.2

Hi,

We have encountered what appears to be a compatibility/regression issue with Elementor 4.3.2 on a WooCommerce site.

The site was working normally previously, with the last confirmed online order placed successfully on 23 September. Elementor was subsequently updated to 4.3.2.

Symptoms with Elementor 4.3.2:

• WooCommerce checkout remains permanently stuck on the loading/spinning overlay.
• Cart functionality is affected.
• The Hootix/Xootix side cart stops functioning and its floating cart icon disappears.
• Some WooCommerce product pages have significant layout/rendering problems.
• The Elementor editor fails to open.

While investigating the checkout issue, I inspected the WooCommerce ?wc-ajax=update_order_review request. The request completes with HTTP 200 and WooCommerce generates a successful response, but the response is malformed.

Instead of beginning with the expected JSON, Elementor-generated CSS is output before it. In our case there were approximately 850 lines of <style> output relating to Elementor templates before the JSON eventually began with:

{"result":"success","messages":"","reload":false,"fragments":{...}}

This appears to prevent WooCommerce from parsing the AJAX response correctly and leaves the checkout loading overlay in place.

I initially suspected ElementsKit because the CSS related to our ElementsKit header/footer templates. However, rolling ElementsKit Lite back to 4.0.2 made no difference. Disabling Elementor (which also disables ElementsKit) immediately restored the WooCommerce functionality.

I then rolled Elementor back from 4.3.2 to 4.2.4.

This immediately resolved all of the above issues:

• WooCommerce cart and checkout work correctly.
• Payment section/Opayo loads correctly.
• Product page layouts are restored.
• Hootix/Xootix side cart and floating icon work again.
• The update_order_review response is clean JSON again, with no Elementor CSS/HTML preceding it.

For example, after rolling back to 4.2.4 the response correctly begins:

{"result":"success","messages":"","reload":false,"fragments":{...}}

The successful response also contains the expected WooCommerce checkout and payment fragments.

Environment/components involved:

• Elementor 4.3.2 – issue present
• Elementor 4.2.4 – issue resolved
• WooCommerce
• ElementsKit Lite (used for header/footer)
• Xootix/Hootix side cart
• Opayo/SagePay WooCommerce payment gateway

This appears similar to other reports of Elementor 4.x causing problems when WooCommerce is active, although in our case there is a particularly clear issue with Elementor output being injected before the WooCommerce AJAX JSON.

Please let me know if you would like any additional debugging information, the complete update_order_review responses from 4.3.2 and 4.2.4, or further environment/version details.
