Change FaceBook back to English from Spanish.

Somehow my wife switched her FaceBook page to Spanish, and I want to get it back to English. I Googled it but the instructions tell me how to do it based on the English menu's, which aren't there now. Or what is posted doesn't jive with what I see on screen. Outdated or something? I need the actual instructions with what is displayed in Spanish, to switch it back. I don't use FaceBook so the more detailed the instructions the better. Any help will be greatly appreciated. She has no idea how she switched it, and she doesn't know anymore about FaceBook settings than I do. My daughter set it all up for her.

Thanks guys, soon after I posted she figured it out on her own. More blind luck that figuring, but its back to English. She spotted "English US, English Canadian, etc" text on the page and clicked English US. That switched it back. It's likely the same spot she clicked by accident in the first place to switch it to Spanish. I looked all over the page and didn't see it? FaceBook is one of the few PC related sites I know absolutely nothing about. Usually I just tell her to ask her daughter how you do, whatever it is she wants to do.
