Site Problems

For some reason, this site no longer works from Netscape/Mozilla. The index page can't be viewed from just http://jdg.blogspot.com, but http://jdg.blogspot.com/index.html will load. Still seems to work with IE or Safari, though. It's not the template -- I swapped out all my changes for a vanilla template and I got the same behavior. This is beyond me to fix.
