To fix the “100 Unsupported Request” error on Facebook, log in through the Facebook Lite app or download an older version of Facebook for Android only; If you have an iPhone, you need to wait until the bug gets fixed within 48 hours.
This bug or glitch usually happens when there is a new update that Facebook has released.
Today, I will teach you how to fix the “100 Unsupported Request” error.
Why You’re Getting the “100 Unsupported Request” Error?
The “100 Unsupported Request” error comes after a new update Facebook has released on both App Store and Play Store.
This error occurs when you upload a post on your business page and Facebook puts it under review.
The reason behind this is that the post has “letters and symbols” that aren’t either supported or suspected to be violating the Terms and Service of Facebook.
However, this message is happening recently with users who are logging in to the app.
This means that there is a bug on Facebook actually, and it’s caused by the new update.
The bug is affecting both the Facebook app and Messenger.
So you may encounter the error when you log in to your website.
How to fix the “100 Unsupported Request Method” error?
To fix the “100 Unsupported request method” error, download an older version of the Facebook app from the APK Mirror website.
By doing so, you’ll temporarily be using the old version of Facebook until the issue gets fixed.
This method works only with Android users.
If you’re an iPhone user, you need to uninstall and then reinstall the app.
Here’s what to do to fix the “100 Unsupported Request” error on Facebook:
- Try logging in using another device;
- Clear the app cache on the Settings for Android (Settings > Apps > Facebook > Storage > Clear App Cache);
- Download an older version of Facebook on the APK Mirror website on your phone (Android only);
- Check if there is a server outage on the “Downdetector” website;
- Wait until the error gets fixed by itself for a maximum of 48 hours.
The five methods above are the most common fixes you can apply to fix the “100 Unsupported Request” error on Facebook.
Keep in mind that it’s a bug happening for now, and it may be fixed in a couple of days.
So you can use Facebook on your desktop or laptop in the meantime.
The desktop version rarely gets hit by the app updates as it’s completely separated from the app platform.
However, they are on the same server, so you may encounter some issues like slow page loading.
You may also see some slight differences in the web page design that may look bizarre.
If you’re still not able to fix the “100 unsupported Request” even after a few days, contact Facebook support and report the issue.
