Hello,

Please try to disable all 3rd-party plugins and check it then.
Make sure you’re using last theme version.
Before update delete “woocommerce” folder in the directory wp-content/themes/classico/ and it’ll be reuploaded from a new theme package.

Also, update all required plugins https://www.8theme.com/download-plugins/ .
