Was working with you theme via localhost and tried to customize my frontpage to hide/remove the sidebar. Went into Customize > Voltata Display Options and clicked on NO SIDEBAR. I checked the frontpage and the sidebar still appeared on the right side. Unfortunately, this also happened when I chose the LEFT SIDE option. So to summarize, the section on displaying sidebar options didn’t want to work.
I wrote because I wanted to remove the sidebar from the frontpage of the site am building. Hope to hear from you soon.
