Confirmed Account was already verified but still cannot access my account

Yesterday I can access my account perfectly, until I asked my sister to check my facebook account for me which is on different location than on the computer I normally used. Today, I received the "confirm your account" message, which I did, through text message but still receive "Please provide a response on security check".

Please help. I even tried using different browser, deleting cache but still the same thing. Right now, I am using different ID. please help

We think there is a Facebook glitch; hopefully Facebook Admin will deal with it whey they return to work today....
