i can't even open FB login page

[millenniumvirus]

By the day I bought this phone, I firstly open FB and I used it for a while. Then I turn off the phone without logging out FB. In the evening, I opened it again but i could not access FB anymore. What should I do? My phone is
SAMSUNG GALAXY S3.

What happens? Do you get an error? Are you using the app or browser? Have you tried restarting your phone?
