The error:

PHP Fatal error: require_once(/home/user/public_html/wordfence-waf.php): 
failed to open stream: No such file or directory

indicates that Wordfence's Web Application Firewall (WAF) file is missing or misconfigured.

Check If wordfence-waf.php Exists

Run this command in SSH or use cPanel File Manager:

ls -lah /home/user/public_html/wordfence-waf.php

If the file exists, check its permissions (see Step 3).
If the file does not exist, proceed to restore or recreate it.

Restore wordfence-waf.php from Backup

Check if your hosting provider has backups.
If you have a manual backup, restore the file from:
- cPanel > File Manager
- FTP client (FileZilla)
- A downloaded backup copy

After restoring, restart Apache/Nginx:

sudo systemctl restart apache2

sudo systemctl restart nginx

Recreate wordfence-waf.php Manually

If you cannot restore the file, create it manually.

Create the File

nano /home/user/public_html/wordfence-waf.php

Add the Following Code

<?php
// Wordfence Web Application Firewall
if (file_exists(__DIR__ . '/wp-content/wflogs/bootstrap.php')) {
    include_once __DIR__ . '/wp-content/wflogs/bootstrap.php';
}

Save the File and Set Correct Permissions

chmod 644 /home/user/public_html/wordfence-waf.php
chown www-data:www-data /home/user/public_html/wordfence-waf.php  # For Apache
chown nginx:nginx /home/user/public_html/wordfence-waf.php        # For Nginx

Restart Apache/Nginx

sudo systemctl restart apache2

sudo systemctl restart nginx

Check & Update wp-config.php

If Wordfence still does not work, verify the WAF settings in wp-config.php.

Edit wp-config.php:

nano /home/user/public_html/wp-config.php

Find and update this line (or add it if missing):

define("WFWAF_LOG_PATH", '/home/user/public_html/wp-content/wflogs/');

Save the file and exit.

Try loading your website again.

Reinstall Wordfence (If Necessary)

If the issue persists, reinstall Wordfence:

wp plugin deactivate wordfence
wp plugin delete wordfence
wp plugin install wordfence --activate

This will recreate all necessary files.

Summary of Fixes

Issue	Fix
wordfence-waf.php is missing	Restore from backup or recreate manually
File exists but still errors	Check file permissions (`chmod 644`)
Incorrect Wordfence settings	Update wp-config.php (`define("WFWAF_LOG_PATH", ...)`)
Wordfence corrupted	Reinstall with `wp plugin install wordfence`

Now Wordfence WAF should work properly again!
