The new blog post editor (Gutenberg) at WordPress.com is still buggy and if you wish to go back to using the old trusted classic WordPress.com editor, Here’s how you can do that;
Login at WORDPRESS.COM
Click “Write” on the top-right hand corner;
Click the three dots at the top-right-hand corner and at the bottom of the menu, click “Switch To Classic Editor”;
Do NOT click the “Write” button on the top-right bar as it will fire up the new editor that you are trying to get rid of. Instead, visit this link to go straight to WordPress Dashboard;
(change “yourwebsite” to your own blog name site address)
Click the “Deactivate Gutenberg” button under “Not quite ready?” and good riddance. Now you can happily (and freely) enjoy using your classic old wordpress editor by clicking the “Write” button at the top-right bar or anywhere on WordPress.com.
Revert Back To Classic Editor On Self-Hosted WordPress Blogs
Login to your WordPress admin;
Visit Dashboard –> Plugins
Install and activate new plugin “Classic Editor” by WordPress Contributors as below;
Note: Please don’t confuse WordPress.com with WordPress.org or the self-hosted wordpress blog. This blog post is about free hosted wordpress.com blogs.
