If you cannot get to Facebook, the site doesn’t open, you get the “Page cannot be displayed” error, an empty page is displayed, you get some sort of SMS activation or anything of this kind, it means the time has come to check your hosts file and clean it up if necessary.
It may turn out that some virus on your computer have made some changes into this file, and the file is very important for your browser and other programs to function correcty. So we need to check if it’s the source of your problem.
If you have Windows 7 or Vista on your computer, start Notepad as an administrator. To perform that, select “Start — All Programs”, find Notepad in Accessories, right-click on it and select “Run as Administrator”.
If you have Windows XP, simply start Notepad.
In Notepad, select “File — Open”.

Try to sign in to Facebook via Favepad.com once again. Most probably, the problem has been solved at this point. The link below takes you to Favepad.com main page. When it opens up, press “Sign in” in the Facebook box.
