Hello,

Thank you very much for choosing our theme and for contacting us.

This is WordPress but, please install the free Classic widget plugin to fix that.

In order to show the sidebar on either of the sides instead of the top, please disable the top filters in the Theme Settings > Shop > Shop filters.

Then enable the sidebar in the Theme settings > Product Archives > Sidebars and add the widgets into Appearance > Widgets > Shop page widget area.

Best Regards
