How to fix an index.php file corrupted on WordPress site

If your WordPress site isn’t looking right because of a corrupted index.php file, here are two easy ways to fix it:

It is always a good idea to save a backup of your site before you tinker with your site’s files.

Option A: Replace the index.php file with a fresh copy

Step 1: Access your WordPress site files using FTP or your hosting provider’s file manager. Look for the folder named public_html.

Step 2: Download the latest WordPress version from the WordPress repository. On your computer, unzip it by double-clicking it if you’re using a Mac or right-clicking and selecting Extract if you’re on a PC. Look for the index.php file in this download.

Step 3: Delete everything except the index.php file from this new download. Then, upload the new index.php file to public_html, replacing the old one.

Step 4: Check your site to ensure everything is displaying how it should.

Option B: Reset the index.php file by pasting code

Step 1: Open the corrupted index.php file with a text editor.

Step 2: Delete all the code in it and paste the default code:

<?php

/**

 * Front to the WordPress application. This file doesn't do anything, but loads

 * wp-blog-header.php which does and tells WordPress to load the theme.

 *

 * @package WordPress

 */

/**

 * Tells WordPress to load the WordPress theme and output it.

 *

 * @var bool

 */

define( 'WP_USE_THEMES', true );

/** Loads the WordPress Environment and Template */

require __DIR__ . '/wp-blog-header.php';

Save the file once this is done.

Step 3: Use FTP or your hosting panel to upload this fixed index.php file back to the public_html. Refresh your site to see if the error has been resolved.
