Hello,

I saw the screenshot you attached.

Please add widgets to the Shop page widget area under Appearance >> Widgets.

And disable the Shop filters from Theme Settings >> Products Archive >> Shop Filters.

Screenshot for Clarification: https://gyazo.com/e4754152903d5c5a208b571ce63aea88

And the Widgets Errors are WordPress problems not related to our theme.

Try to install Classic Widgets plugin to fix this problem for now https://wordpress.org/plugins/classic-widgets/

Regard’s.
