Restore Facebook Language Settings: How-To

To restore your Facebook language settings, go to Settings & privacy > Language and choose “English (US)” or your preferred language, then click Save changes. If your feed is still showing the wrong language, clear your browser cache or check your device’s system language, which Facebook sometimes follows by default.

Why Facebook Language Settings Change Unexpectedly

Facebook determines the display language from several sources, and a mismatch between them can cause the interface to switch without you noticing. The most common triggers are:

Device system language: If your phone or computer is set to another language, Facebook may adopt it for new sessions.
Browser or app locale: The language of your browser (e.g., Chrome, Safari) or the Facebook app’s own setting can override your account preference.
VPN or network location: Connecting through a VPN in another country may prompt Facebook to suggest or apply that region’s language.
Accidental change: A misclick on the language picker or a friend using your device can switch it.

Understanding these sources helps you fix the root cause, not just the symptom. For instance, if you only change the in-app setting but your phone’s system language is Spanish, Facebook may revert to Spanish after an update or reinstall.

How to Change Language on Facebook (Desktop)

On a computer, the steps are straightforward. Follow these exactly:

Click your profile picture in the top-right corner.
Select Settings & privacy, then Language.
Under Language, click Edit next to “What language do you want to use to translate posts?” (this is for translations) or scroll to Display language.
Choose your language from the dropdown (e.g., English (US)).
Click Save changes. The page will reload in the new language.

If you don’t see the Language option under Settings & privacy, click Settings directly, then Language and region in the left sidebar. The menu names may vary slightly with Facebook’s frequent UI updates, but the path is consistent.

How to Change Language on the Facebook App (Mobile)

The mobile app uses a slightly different menu. Here’s how to do it on both iOS and Android:

Tap the hamburger menu (three lines) at the bottom-right (iOS) or top-right (Android).
Scroll down and tap Settings & privacy, then Language.
Tap Language again and select your preferred language from the list.
The app will immediately reload in that language.

Note that on some Android versions, you may need to tap Settings > Preferences > Language. If the app still shows the wrong language after this, force-close the app and reopen it.

What to Do If the Language Keeps Reverting

If you’ve changed the language but it reverts after a day or a week, the issue is likely outside your Facebook settings. Try these fixes in order:

Check your device’s system language: On iPhone, go to Settings > General > Language & Region; on Android, Settings > System > Languages & input. Set it to the same language as your Facebook preference.
Clear your browser cache and cookies: For Chrome, click the three-dot menu > Settings > Privacy and security > Clear browsing data. For Safari, go to Preferences > Privacy > Manage Website Data and remove Facebook’s data.
Update the Facebook app: Outdated versions sometimes ignore language settings. Check the App Store or Google Play for updates.
Disable VPN or proxy: Temporarily turn it off and see if the language sticks. If it does, the VPN’s location is the culprit.
Log out and log back in: This refreshes your session and often re-syncs your preferences.

If none of these work, try using Facebook in a different browser (e.g., Firefox instead of Chrome) to isolate whether it’s a browser-specific issue.

Common Mistakes and Misconceptions

Many users confuse the translation language with the display language. The translation setting only affects posts written in other languages—it doesn’t change the menus. Always look for “Display language” when you want the interface changed.

Another misconception is that changing your phone’s language will automatically change Facebook. That’s true only if you haven’t explicitly set a different language inside Facebook. Once you set a display language in Facebook, it overrides the device language—until a major app update resets it.

Also, be aware that Facebook may show a banner asking “Do you want to translate this post?”—that’s not a language change, just a translation prompt. Clicking “Not now” won’t affect your settings.

How to Set a Default Language for Posts You See

Beyond the interface, you can control which language’s posts are prioritized in your News Feed. Go to Settings > Language and region and look for Preferred language for posts. Choose the language you want to see most. This doesn’t hide other languages—it just boosts posts in your chosen language. This is useful if you’re bilingual and want to see more content in one language.

Frequently Asked Questions

Why is my Facebook suddenly in another language?

This usually happens because your device’s system language changed (e.g., after an OS update) or because you used a VPN in another country. Facebook may apply that locale automatically. Check your device settings and reset your Facebook display language as described above.

How do I change Facebook back to English on my iPhone?

Open the Facebook app, tap the hamburger menu, go to Settings & privacy > Language, then tap Language and select English (US). If it doesn’t stick, also change your iPhone’s language to English in Settings > General > Language & Region.

Can I have Facebook in two languages at once?

Facebook doesn’t support a true bilingual interface. You can set the display language to one language and the translation language to another, but the menus will only appear in one language. For posts, you can set a preferred language, but you’ll still see posts in other languages.

Why does Facebook keep resetting my language to Spanish?

If you’re in a Spanish-speaking region or using a VPN with a Spanish IP, Facebook may auto-detect and apply Spanish. Also, if your browser’s language is set to Spanish, that can override your Facebook setting. Change both your browser and Facebook language to English, and clear your browser cache.

How do I change the language for Facebook comments and posts from others?

That’s controlled by the Translation language setting. Go to Settings > Language and region, click Edit next to “What language do you want to use to translate posts?” and choose your language. This will show “See Translation” links under posts in other languages.

Does clearing the Facebook app cache delete my language preferences?

No, your preferences are stored on Facebook’s servers, not in the cache. Clearing the cache only removes temporary files and may actually help if the app is displaying outdated language data. Your settings will remain intact.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
