Hello There,
Thanks for writing in! Upon checking your site, you have selected the Icon stack. Please keep in mind that this Icon stack has a default fixed left or fixed right sidebar. This is what is being displayed right now. If you want to have a fullwidth with no sidebar layout, please go to the customizer, Appearance > Customize > layout & Design > Content Layout and select “Fullwidth”. If you do want to have a sidebar, a normal sidebar. Please try the other stacks instead.
Hope this helps. Please let us know how it goes.
