Since Gutenberg is now built into and part of WordPress, not everyone wants to use the block editor. Because this is now the default editor, you still have the option to install a plugin called Classic Editor.
Ariele still has a setting that disables the theme’s block styles, although it’s not as comprehensive as the latest plugins that are now available.
- Go to Appearance > Customize > Ariele Theme Options > Basic Settings
- Look for the Disable Gutenberg Styles setting and toggle it on (blue) to disable
- Click the Publish button

Once you disable the block styles, no more block styles will load, which helps speed up your website. From this point, just keep the classic editor as your default one.
IMPORTANT: Remember when disabling the block styling, anything that was using blocks will now be unstyled and no longer available. This means anything that uses blocks and is shown on the demo for this theme, will not be possible.
UPDATE: We’ve recently written an article on How to Disable the Block Editor. It guides you through the latest methods to disable it and to put the Classic Editor back.
We have recently written an article on how to disable the block editor, as well, most of the Gutenberg features.
