Hi Randolph, just as you email came in I have managed to get it working.
I had been clicking the update button but no changes were made to the live page or even to the preview page.
In desperation I went back and re-installed the site files and noticed ther was no . HTACCESS file. When I created a base one, every thing worked!!
I don’t know why but thanks very much for taking an interest. This is my first WordPress effort, so I have a lot to learn.
