I have created a new page, which I am wanting add to our Main Menu. when I add it, although when creating it has new content, the preview and live is just duplicating the ‘about us’ page content.
I’ve tried a couple of new pages, all with the same result.
Ideally, you already have a page template that is not hard coded. Every theme comes with a default page template to use.
If this is the case, I would simply assign this template to the page you’re are trying to build out.
If your default page template was overwritten, it’s simply a matter of adding it back. You can just copy the code from the original theme (or even, perhaps, a different theme) and create a new page template.
