I originally downloaded one of the free template and then modified the main the structure with my changes; bkground colors and logo.  I can see the index page showing the changes in preview mode, but when I uploaded the page to the website or view it in a browser, it shows the old format.  Also if I go into the directory and click on the index file, it brings up the old format in the FF browser. How come the new format is showing only in preview mode. I have exported the files for upload.
