How to Disable the Block Editor (aka Gutenberg) and Use the Previous WordPress Editor
WordPress 5.0 brings a number of changes, but none is more significant than the new block editor, which you might also know as Gutenberg (its name while under development). If you don’t like the new editing experience in WordPress 5.0, you might be wondering if you can return to the previous WordPress editor instead.
While you don’t want to miss this update altogether, it is possible to avoid the new editor itself. This involves installing the Classic Editor plugin, which will preserve the experience you’re used to. It’s important to note, these solutions will most likely not be a long-term solution. WordPress is pushing the Gutenberg editor and you’ll need to most likely adopt it at some point. The WordPress team has said that the Classic Editor plugin will only be officially supported until December 31, 2021.
