“100 Unsupported Request Method Type Post” on Facebook (4 fixes)

Are experiencing Login failed error as you try to login to your Facebook?

The other part of the message states on screen; 100 unsupported request method type post.

This error has been reported by many Facebook users across several platforms.

Via Reddit;

In this guide, I will show you how to fix this post problem.

But before we start the process let us understand why does Facebook say “Unsupported request”?

What does Facebook say unsupported request mean on Facebook

Facebook says unsupported request mainly due to a bug or glitch in the app. This would mean you have to wait-out 12-24hours until the problem is fixed.

To check if Facebook is down, you can use a down detector to check its status.

This shows the reports of Facebook status reported in the last 24hours.

The other cause for this could be Facebook app storage being full.

Clearing the app data storage would help solve the problem.
