Reply To: Error in cart after order

Hello,

Please make the full backup of your site and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.

If you see the same on the Storefront, deactivate all the plugins except these ones:

Slider Revolution
WPBakery Page Builder or Elementor
Woodmart Core
Contact Form 7
MailChimp for WordPress
WooCommerce
Safe SVG
Switch to the parent theme and check the issue.

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

Best Regards
