Please do not send me to look at the documentation. This issue does not appear to be addressed in the documentation.
I successfully created a home page. I wanted to add another page so I clicked on 'create new'. This indeed created a new page. However, the new page was a copy of the home page, except that at the bottom I could add text or other elements. None of the elements of the home page (which were duplicated on the new page) could be selected for deletion or anything else.
I don't understand how this works. I tried over and over to create a new page and a new page was added to my menu, but the top portion was always an uneditable copy of the home page.
