Hi Team, thanks for your response.
Toufiq, I'm going to watch the video and look for the solution, because I want to continue with the main menu I have from the template.
Pavel, how can I publish through a special SP PB menu item? Do I have to create a main menu with SP Page Builder? Because as I said I want to continue with the menu that I already have.
In fact, I made a copy of the service page with SP Page Builder. This service page was created with SP Page Builder and which is ready to use in the template, it is also linked to the main menu and works correctly. With this copy, I am working on the page of one of the company's services, that is, it is a page made with SP Page Builder and even so, having created the link within the button, when I access the page, page not found message appears. As you see, I created the page wiht SP Page Builder.
Images attached.
Thanks guys.
Regards.
