Reply To: Action after adding to cart no longer works after update

Hello,

Please deactivate all the plugins except these ones:

Slider Revolution
Elementor, Elementor Pro should be also deactivated.
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
Switch to the parent theme.

If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.

Best Regards
