Cannot log into Facebook

Hello, I have problem to login with one of my profiles in facebook.
When I try to login I got blank page and url: https://www.facebook.com/checkpoint/?next

I tried to change browser and also to login from m.facebook.com but the same problem appeared.
I've received one message from facebook that is reported for copyright one video in my fan page, but I can't check it because it appeared blank page.
