Go to a computer with an internet connection.
Start a web browser program (Internet Explorer, or Mozilla Firefox, or other programs of similar type, are all web browsers.)
Enter, in the Address field (not the Search field!) the address:
and press the RETURN key on the keyboard, once.
Then enter the username of the Facebook account.
Then enter the password ***** the Facebook account (both of those into appropriate fields on the web page, for logging into or signing into your Facebook account.)
Then try to sign in, log in, by submitting the username and password.
See if that allows access to the Facebook account. If it does, the account status is not the problem.
