How to Change the Language Back to English on Facebook
Did you set the language of your Facebook account to something you don't understand and now you want to have it again in English? This guide will show you how to do it.
At the very bottom of any page on Facebook, on the left side, you will be able to read the word 'Facebook' followed by a copyright sign and the current year. Right next to it, there is a link written in the current language of your Facebook account. Click on that link.
Once you have clicked on it, you will see a new window with all the available languages. Now you just have to click on the English version you would like to have and automatically you will have your layout back to normal.
In the picture used in this example the link is in Japanese, but this works for any given language
