Why did an unexpected error occur on Facebook?

It can also happen because there is a Facebook outage (the servers are down).
You can check if the app is down by searching for “Facebook” in DownDetector or using Twitter.
If there’s a spike in the number of reports, it means that Facebook is most likely down.
If Facebook is down, you need to wait for the servers to be back up.

How to fix “An unexpected error occurred” on Facebook
To fix “An unexpected error occurred” on Facebook, you can try clearing the app’s cache, creating a new account using the same login details, or installing an older version of Facebook.
You can also try updating Facebook to the latest version or uninstalling and reinstalling it.
If all else fails, it means that the servers are down and you need to wait for 24 to 48 hours.
You can check if Facebook is down on DownDetector.com and the latest tweets on Twitter.
Do not reset your phone settings because they will not work.
Fix 1: Clear Facebook’s cache
To clear the cache on an Android device, open the Settings app > Apps > Facebook > Storage > Clear Cache > Clear Data > re-open Facebook.
To clear the cache on an iOS device, open the Settings app > General > iPhone Storage > TikTok > Offload App.
By doing so, certain issues on the app will be fixed like loading or logging in.
You can also uninstall and reinstall Facebook to clear its cache.
In addition, the app will be updated to the latest version.
Fix 2: Create a new account using your existing login details
- Open the Facebook app and create a new account.
- Enter your existing email and password.
- Enter the same name, same birthdate, and create the account.
- Your existing Facebook account will now open.
Creating a new account using your existing login details is a fix mentioned by a Redditor.
Many users claimed that they managed to fix the login issue, “An unexpected error occurred” by doing this:
“It worked, I’ve been locked out for almost 2 years”.
“This actually worked for me thank you so much!”.
“After almost a year, I got mine back”.
Fix 3: Install an older version of Facebook
- Go to https://facebook.en.uptodown.com/android.

Fix 4: Update Facebook to the latest version
Updating Facebook is a recommended troubleshooting method by Facebook themselves (via the Help Center).
If you’re having trouble with downloading the app, try switching your network.
That said, some updates contain bugs and glitches.
Facebook will address them in a follow-up update.
If you’ve already updated Facebook to the latest version, you need to wait for a new one.
Fix 5: Wait for a few hours
If all else fails, it probably means that Facebook is down for everyone.
If that’s the case, wait for a few hours for the servers to be back up.
