Hello,

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

In case, the problem remains, even after all the plugins are deactivated, You need to increase PHP max input vars parameter on your server to 10000 and test how it works. You can ask your hosting provider for help on this matter.

I await your response.

Best Regards.
