The first way you can employ to disable the Gutenberg is using the Classic Editor plugin which is developed by the core WordPress contributors. This plugin allows you to keep both the Classic Editor and the Gutenberg.
After you install and activate this plugin, in Settings > Writing, you will quickly see an option called: Default Editor for all users. In this option, you can select to use the Classic Editor or the Block Editor (Gutenberg).
If you want to select the editor system for each user, go to Users > All users > Open each user and choose one.
Another solution you can use to disable the Gutenberg is using Disable Gutenberg plugin. If you only want to disable this feature for some certain post types, template or post IDs, this is the right plugin for you.
You can install and activate this plugin normally via Plugins section. After that, you will find out lots of configuration options in Settings > Disable Gutenberg.
In this part, the Gutenberg is disabled entirely on your site as default. Nevertheless, you can choose specific user roles, post types, theme template or individual posts you want to use this new visual editor by unchecking the corresponding options.
For themes supporting WPBakery Page Builder plugin such as TemPlaza's WordPress themes, you make sure that you are using WPBakery Page Builder version 5.6. By using this plugin version, you don't need to do anything. You can easily see options to switch among WordPress Classic Editor, WPBakery Editor (Backend and Frontend Editor) and Gutenberg when editing a post/page.
You can also disable the Gutenberg entirely by checking the option "Disable Gutenberg Editor" in WPBakery Page Builder > General Settings.
The Gutenberg is a big difference in the WordPress Core. Although it is expected to bring more convenient for users, lots of them are not familiar with this new visual editor plus many themes are not compatible with it. We hope that you can disable the Gutenberg easily by using one of 3 simple ways above; get everything back the right track.
