How to disable Gutenberg editor from Multisite Admin panel?

Question

I recently Updated WordPress to 5.2.2 and I want to disable Gutenberg editor from network. By this way, I do not need to go into each sites and disable one by one.

I have already installed Disable Gutenberg plugin but this plugin would not show any relevant option to disable through the network level.

Answer 1

You can programmatically disable Gutenberg network-wide by adding a must-use plugin containing this code:

<?php
add_filter( 'use_block_editor_for_post', '__return_false' );
