If you already have the WPBakery Page Builder plugin installed and activated on your WordPress installation and try to install and activate the new WP Gutenberg Editor, you will find out that neither of them works. The Gutenberg editor displays WPBakery shortcodes as plain text and there is no way to switch to the Page Builder editor using the Backend Editor button, as was the case with the old WordPress (TinyMCE) editor. Thankfully, we’ve got an easy workaround for that:
Log in to your installation, go to Dashboard > Plugins and click Add New.
Then, on the search field look for Classic Editor from WordPress Contributors
Install and Activate the plugin
Go to Dashboard > Settings > Writing and make sure that the “Replace the Gutenberg editor with the Classic editor“ is selected.
Alternatively, you can select the option to “Use the Gutenberg editor by default and include optional links back to the Classic editor” if your work is not dependent so much on Page Builder and, you are planning to use the new editor.
Save changes and check your website.
At this point, the Page Builder Backend option should have been restored and you will now be able to continue your work as usual.
