I'm using Cornerstone, and want to be able to advertise on each side of the boxed layout. Can you give me a solution?
Boxed layout as my old test site here:
That is not possible in X but possible in Pro using side headers. You might want to upgrade to Pro.
I can see that i have "PRO" under licences, but thought I had "X theme".
Can you guide me how to add the bars for ads?
Please see this tutorial https://theme.co/apex/forum/t/pro-header-and-footer-builder-introduction/103. That will introduce you on how to use the header and footer builder. Once you know how to use the builders, you can setup a left and right header with Text element or elements of your choice.
