Hi JC,
Could you let me know how I can remove the entire right sidebar?
You can do this by creating a Layout Element on WP Admin > Appearance > Elements.
Set the Sidebar Layout to Content (no sidebars) and set the Display Rules Location to Page > Shop.
To add:
if that doesn’t work, you can go to WP Admin > Appearance > Layout > Woocommerce .
You should also see a Sidebar Layout. Set it to Content (no sidebars)
Secondly, if I were to keep the right sidebar, but remove the Archives widget from it, how would I go about doing that?
This is added by WordPress by default when sidebar widget area is empty. We can remove the archives widget by placing any widgets to the sidebar.
If we want an empty sidebar, we can place a empty custom HTML or text widget so it displays nothing.
