WordPress 5.8 will turn the classic widget screen into the block-based widget screen. While this is a transitioning move, it might create compatibility issues for some sites.
The following snippet can be used to restore the classic widget screen:
add_filter( 'gutenberg_use_widgets_block_editor', '__return_false' );
add_filter( 'wp_use_widgets_block_editor', '__return_false' );
In case it helps, here’s how to add custom codes in your site.
If you’d want to use it as a plugin, you can download the Classic Widgets plugin by the WordPress team.
That’s it. I hope this helps!
Did you know? You can alert your website visitors about their lost internet connection
Thank you!
