If you have been following these posts, you'll have seen that my home page has looked rather fragmented for a day.
I have been experimenting with the layout:-
copying a theme and then modifying it for my own use
creating a new home page template, based on the index page but modified
creating a new footer
creating a new post template, called post1, which will show on the home page only
In fact, it was errors in the new home and post1 templates which have caused the fragmented look. I made my first set of changes and uploaded them with a reasonable degree of (misplaced!) confidence and no time to test and fix.
So, we have now swapped back to the original index page and now I will work through things slowly, so that I catch any errors I introduce....
