If you have gone in to edit one of your pages or posts and seen your editor looks like this:
This means that your site has the newest version of WordPress which is version 5.
Either you updated it or very likely your host updated it automatically for you.
Wordpress 5 comes with Gutenberg, a new editor that is jam packed full of new features for your editor. However you may not want to learn something new right now.
Divi offers a one click solution to remove it for all pages and posts.
First you must ensure Divi is updated to the latest version.
Then go to the Divi menu item ( the left, towards the bottom) -> Theme Options.
In the tabs at the top click Builder -> Advanced.
Then Enable the Classic Editor.
Click “Save Changes”.
Then when you return to the page or post editor you will see that it has gone back to the classic editor.
