This is strange indeed. I visited "http://www.oldhouseforums.net/nohfbbs/wwwthreads.php" and "http://www.mmogzone.com/wwwthreads/newuser.php" with netscape 4.77 / mozilla 0.9.3 / ie 4.01 and everything worked fine. Are you sure you don't have a leftover language cookie or some file in the language directory is not readable by the webserver?
