I've read the dedicated forum and similar issues to this elsewhere, but can't find a simple solution.
In short, the right sidebar reads "in Archive" even when switching the page layout to full width: http://rhodeblocks.com/shop.
Can I get rid of this sidebar by editing the existing files, without having to create a child theme or duplicate files for altering? I'm not an advanced editor, but I'm a quick learner. I just want the easiest workaround to get the full width page to actually work.
