Fix WordPress error showing Localhost IP address

On a regular web server, WordPress doesn’t have any problems with correctly displaying the IP addresses of site visitors or commenters, ….

However, on some other servers, WordPress may not display the correct IP address in the comments dashboard or other locations. Instead, WordPress shows the IP address of Localhost as 127.0.0.1. So this article Emergenceingames.com will show you how to fix WordPress error showing Localhost IP address on user comments.

Fix incorrect IP address on WordPress

Note: Before editing any file in WordPress, you should create a backup file to avoid possible bad situations.

The simplest way to solve this problem is to add a code snippet to the “wp-config.php“. To do this, you open the FTP client, then log in to your FTP account and open the file wp-config.php.

After opening the file, copy the code snippet below and paste it at the end of the file:

// Code for showing correct client IP address

if ( isset( $_SERVER[‘HTTP_X_FORWARDED_FOR’] ) ) {

$mte_xffaddrs = explode( ‘,’, $_SERVER[‘HTTP_X_FORWARDED_FOR’] );

$_SERVER[‘REMOTE_ADDR’] = $mte_xffaddrs[0];

}

Then save the file and re-upload the file.

From now on you will see the real IP address of the client on the WordPress comment page and other locations, that’s it, you have fixed WordPress error showing the Localhost IP address on user comments successfully.

What happens to Code Snippet?

When a WordPress site is behind an HTTP proxy or uses a load balancer, an HTTP called “X-Forwarded-For” is used to store all IP addresses including the actual client IP address in a string. .

By default, the IP address in X-Forwarded-For is separated by commas, and the first IP address in the string is always the IP address of the client.

What we do with the code snippet above is to get all those IP addresses, split them into separate parts and store them in an array. $mte_xffaddrs. Since the first IP address is related to the client, we can use the index Zero and point it to REMOTE_ADDR in array $ _SERVER.

Fix incorrect IP address on WordPress using Plugin

If you don’t want to touch the core WordPress files, you can use a plugin called Proxy Real IP. Although this plugin hasn’t been updated for a long time, it still works pretty well. Basically this plugin works like the code snippet above. The only difference is that the Real IP Proxy plugin uses the preg_match not a function explode.

Just install and activate the plugin just like you would with other plugins. There is no settings page or options to configure.

Fix incorrect IP address on WordPress using Cloudflare

When behind a proxy like Cloudflare, WordPress may sometimes show the Cloudflare IP and not the visitor’s real IP or the Localhost’s IP address.

There is a simple way to fix this problem. Just paste the below code at the end of the file wp-config.php:

// Fix incorrect IP when using Cloudflare

if ( array_key_exists( ‘HTTP_CF_CONNECTING_IP’, $_SERVER ) ) {

$_SERVER[‘REMOTE_ADDR’] = $_SERVER[‘HTTP_CF_CONNECTING_IP’];

}

The above code gets the real IP address of the client using HTTP_CF_CONNECTING_IP and points REMOTE_ADDR to that IP address.
