sidebar design

Hi,

I’m trying to change the design of below the header sidebar, but it just doesn’t work. I want to add sidebars to different brand pages and customize the color to the brand.

I have pro version, I go to the desgin tab, change the color, but once I save it, it changes back. And, of course, no changes to the site.

Could you help me?
