Hello,
Please restore the site from the backup, we do hope you have made it and 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
Then update the theme, then plugins in Appearance > Install plugins, and then activate other plugins one by one to detect which one cause the problem.
In case, the problem remains, even after all the plugins are deactivated, provide your site admin access (insert the site credentials into the Private content block under the message area) and confirm the permission for plugins deactivation, switching to the parent or default theme. As soon as we complete the testing we will enable all back, however, the site would be without plugins for 15-20 min. You would better make the full backup of your site.
Best Regards
.
