I have lost all navigation on my site
I think the problem started when I tried to add some google web stats to my index.php at the end of the file just above the /body tag.
This gave my site a 404 error so I removed my edit. All returned and seemed to be normal until I discovered that the links do not work. The nav bar indicates a new page but it refreshed the index.php
One thought is that the index.pxp has lost reference to the associated database.
Any help well appreciated, as I am lost.
