My site is designed with FrontPage 2003. I purchased a shopping cart that requires a Unix server. For some unknown reason, the navigation structure becomes corrupt as it sits on the server. The navigation bars and page formatting will either be missing, or some navigation bars will be fully functional while others will be present, but missing the labels. The problem is not consistent. The host claims it is not what he is doing, but the problem occurs when he has made modifications to the site address, or when he installed a trial SSL. When I access the site with FrontPage and view the problem navigation bars, t hey appear normal.
