Hi Steve,
Thanks for reaching out and thanks for using BoldGrid Post and Page Builder for WordPress!
I tried inspecting your website but I see it’s password protected. You should be able you get your content to display full width by using the Customizer to navigate to Design < Pages < Container and you will see a toggle for Contained or Full Width.
Select Full Width there and it should enable the functionality. The same toggle exists for Posts as well. Please let me know if that solves your problem.
I hope this helps. Please let us know if you need further assistance.
