I have about 20 pages in SS which are all named I added a new page and renamed it but when I preview it in html is does not display the page name it displays page 21 - I have deleted the page and made a new one same problem. I sut down the computer and tried again...same problem. It just started hapening today

There are two independent places to set a page name:

1. The drop-down page list on the top toolbar (or Page Editor > Page Select tab). You have probably done this one.

2. Page Editor > Title, MetaTags tab > Page Title. You have probably missed this one and it is still using the default, which is the original page name.

The second one is important because it appears on the browser title bar and other places -- search engines use it too. So make it a good one
