Classic Editor is an official plugin maintained by the WordPress team that restores the previous (“classic”) WordPress editor and the “Edit Post” screen. It makes it possible to use plugins that extend that screen, add old-style meta boxes, or otherwise depend on the previous editor.

Classic Editor is an official WordPress plugin, and will be fully supported and maintained until 2024, or as long as is necessary.

At a glance, this plugin adds the following:

• Administrators can select the default editor for all users.
• Administrators can allow users to change their default editor.
• When allowed, the users can choose which editor to use for each post.
• Each post opens in the last editor used regardless of who edited it last. This is important for maintaining a consistent experience when editing content.

In addition, the Classic Editor plugin includes several filters that let other plugins control the settings, and the editor choice per post and per post type.

By default, this plugin hides all functionality available in the new block editor (“Gutenberg”).

1. 

   Admin settings on the Settings -> Writing screen.

2. 

   User settings on the Profile screen. Visible when the users are allowed to switch editors.

3. 

   “Action links” to choose alternative editor. Visible when the users are allowed to switch editors.

4. 

   Link to switch to the block editor while editing a post in the classic editor. Visible when the users are allowed to switch editors.

5.
