1. Check the proxy setting in IE, enter the tools menu and go to internet option, then select Lan settings in connection window, finally unselect proxy, but the problem still exists.
2. Check port status in window, the command is netstate -ano, port 8080 is the port of webserver, it's vacant. so this isn't the reason.
3. Check folder name of U2000, it is the default name.
4. Check browser status, found that the defaut browser is safari, then set IE as the default browser. Then restart U2000, the problem disappeared and all menu displayed normally.
