How to use the WordPress Classic Editor
                     WordPress Classic Editor
Introduction
Sometimes change is scary. And for those of us who
started using WordPress a long time ago, we’ve been
through some big changes.
It’s one of the biggest changes that brought about the
need for the WordPress Classic Editor.
Evolution of WordPress
WordPress found itself in a bit of a damned if you do and damned if you don’t
situation. Because the platform desperately needed to be revamped.
It hadn’t started out as the powerful CMS it had become. Versions 4 and all
subsequent versions used the WordPress Classic Editor - which is just a nice
way of saying the old one—and for small jobs, it was sufficient.
What Changes Did Gutenberg
Bring to WordPress?
Although it might not have seemed like in the beginning, Gutenberg did and
does make things easier than the WordPress Classic Editor did.
First, it does not change the way WordPress functions under the lid. All it
does is make it easier for creators and site owners like you and me. 
Simply by changing the way we interact with it. Using the Classic Editor
meant all those messy meta boxes and using shortcodes. But all those blocks
that seem intimidating at first, take all that away.
Why was the WordPress Classic
Editor Created?
The shock of the 4.9 to version 5 update must have been enormous. Suddenly,
administrators didn’t know how to add or edit posts.
Yet another problem with Gutenberg was sites that relied heavily on plugins to
function as expected. Because all of a sudden there was a new editor and not
everyone bothered to update their plugins to work with it.
However, the powers that be at WordPress clearly realized they had to do
something to keep a huge segment of their user base happy. Users were staging a
revolt. And this happened even before the official release of Gutenberg.
What is the WordPress Classic
Editor?
The WordPress Classic Editor was the original editor found in WordPress prior
to the release of version 5. It was part of the WordPress core files. Now, the
WordPress Classic Editor is merely a plugin, no longer a part of the core files.
For many, the old default WP Classic Editor was sufficient. These are people
who typically add short, text-heavy blog posts. In other words, their content is
limited to words. Since the old editor is much like a simple text editor you would
find in word processing software, it’s a perfect choice.
How to Use the WordPress
Classic Editor
If you’re new to WordPress, you might not be familiar with its classic editor. And
if you’re finding the new block editor difficult, you might want to revert to the
classic editor while you can.

Conclusion
And if you’re not ready to take the plunge, you can still
use the WordPress Classic Editor—for now. Remember,
WordPress has stated they may not maintain it
indefinitely.
