This problem Cause I install K9 Web security. I am sure because I haven't installed anything when I installed it.
How I solve this :-
I download the setup again from the site. I install it again (without uninstall old, maybe this way you don't need to set up it again).
Now if you sign-out and logged once again you got it working.
Thanks to Ramhound for his comments to fix this trouble.
