Reinstall WordPress Core via CLI

Reinstalling the WordPress core files via WP-CLI is a fast way to fix corrupted core files or remove suspicious code from your installation.

Always create a backup of your website before proceeding. Reinstalling core files cannot be undone.

Reinstall the core files

Log in to your server via SSH. If you're not sure how, follow this guide.
Navigate to the root directory of your WordPress installation:
bash
```
cd public_html
```
Verify you're in the correct directory by checking for the wp-config.php file.
Optional but recommended: Delete the wp-admin and wp-includes directories before reinstalling. This helps remove any unwanted or malicious code that may have been injected into the core.
bash
```
rm -rf wp-admin
rm -rf wp-includes
```
Reinstall the WordPress core files:
bash
```
wp core download --force
```
Update the database if needed:
bash
```
wp core update-db
```

Your core files are now successfully reinstalled.
