WordPress disable file editing is a must-do security tweak. With one simple line in your wp-config.php, you can block theme and plugin editing from the dashboard — no plugin needed!
Add this to your wp-config.php file before /* That's all, stop editing! */:
define( ‘DISALLOW_FILE_EDIT’, true );
How It Works
This WordPress disable file editing trick uses a built-in constant. When it’s set to true, WordPress removes the Theme and Plugin Editor from the wp-admin menu.
Why WordPress Disable File Editing?
Direct file editing is risky. If a hacker gains admin access, they can inject malicious code. Disabling file editing closes this door and makes your site safer.
Common Mistake
Many users add this too late in wp-config.php. Always place it before the “stop editing” comment. Also, remember: this blocks the built-in editors only — FTP or file manager access stays active.
Pro Tip
Combine this with secure file permissions and a good backup routine for maximum protection.
