This is a lightweight WordPress plugin that adds an extra confirmation dialog when clicking the Publish button in the Classic Editor, helping to prevent accidental publishing. Never publish by accident again!
This plugin adds confirmation dialogs for publishing actions in the Classic Editor. 
When working with page builders such as Elementor, WPBakery, confirmations are displayed when publishing or updating content via the WordPress editor controls rather than the builder’s own interface.

Have you ever accidentally published a post before it was ready? Yeah. It sucks. This plugin takes care of that.
When you hit the “Publish” button after writing a post, a small dialog box appears asking you if you’re sure you want to publish the post. You can either click OK or CANCEL. And that’s it! Super simple and no more acidentally published posts.
