Issues with /public_html/wp-includes/functions.php

This problem may be a plugin or theme conflict. Please attempt to deactivate all plugins and switch to the default Twenty Twenty-Four theme. If the problem goes away, re-activate them one by one to identify the source of the problem.

If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to deactivate all plugins and change the theme for you while you’re still logged in without affecting normal visitors to your site.

Try following steps to fix this issue with the /public_html/wp-includes/functions.php file on your WordPress site:

1. Backup Your Site: Always create a backup before making any changes.
2. Check the Error Message: Look at the specific error message you’re receiving. It can point to a line number or function causing the issue.
3. Replace the File:
   • Download the latest version of WordPress from the official website.
   • Extract the files and navigate to the wp-includes folder.
   • Replace the functions.php file on your server with the fresh one from the downloaded WordPress package.
4. Disable Plugins: Sometimes plugins can cause conflicts with core files. Temporarily disable all plugins by renaming the plugins folder in /wp-content to something like plugins_old. If the issue is resolved, reactivate plugins one by one to find the culprit.
5. Check for Code Edits: If you or someone else recently edited the functions.php file, review those changes for errors.
6. File Permissions: Ensure the file has the correct permissions. Generally, 644 is recommended for .php files.

If you’re unsure, you might want to contact your hosting provider or developer for further help.

1. Check for Malware or Hacks:

If the /wp-includes/functions.php file was modified by an attacker, your site might be compromised. To check for this:

• Scan your site for malware using a security plugin like Wordfence or Sucuri.
• Look for unexpected code or file modifications in /wp-includes/functions.php or other core files.
  
  2. Check Error Logs for Details:
  To enable WordPress debugging, add the following to your wp-config.php file:
  

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

This will create a debug.log file in your /wp-content/ directory where you can see error details.

Since the functions.php file in /wp-includes/ is part of the WordPress core, you should never modify it. If this file has been edited or corrupted, it’s important to restore the original version.

How to fix this:

• Reinstall WordPress Core Files:
  1. Access your site via FTP or your hosting control panel’s File Manager.
  2. Download a fresh copy of WordPress from www.ads-software.com.
  3. Extract the downloaded files and upload the /wp-includes/ folder from the fresh copy to your website’s root directory (/public_html/), overwriting the existing /wp-includes/ folder.
  This will restore the default functions.php file along with the other core files in /wp-includes/.
