Thank you for quick update! Have a nice weekend.

Also you might want to update how you read user IP. For users like me who are using cloudflare on their server, your plugin was showing the server IP as the user IP.

Here’s code from another plugin WP-PostRatings that correctly returns user IP.

public function getRealIPAddr() {
	foreach ( array( 'HTTP_CF_CONNECTING_IP', 'HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR' ) as $key ) {
			if ( array_key_exists( $key, $_SERVER ) === true ) {
				foreach ( explode( ',', $_SERVER[$key] ) as $ip ) {
					$ip = trim( $ip );
					if ( filter_var( $ip, FILTER_VALIDATE_IP ) !== false ) {
						return esc_attr( $ip );
					}
				}
			}
		}
}

Okay, I have added the shortcode [ratemypost] to below post. Please check and let me know once you’re done with your analysis.

Also Tabby Responsive Tabs plugin seems to be broken when I add [ratemypost] to this post. C++ and Java section should be displayed as tabs like in other pages.

It’s https://www.techiedelight.com/

I’m also using ithemes security plugin (https://wordpress.org/plugins/better-wp-security/) which is reporting the IP correctly. Below’s the source code they’re using to read user IP. I’m not familiar with PHP, could you take a look please and let me know if you can change anything from your side or I can change anything in my wg-config.php file?

/**
 * Returns the actual IP address of the user.
 *
 * Determines the user's IP address by returning the forwarded IP address if present or
 * the direct IP address if not.
 *
 * @since 4.0.0
 *
 * @return  String The IP address of the user

public static function get_ip( $use_cache = true ) {
	if ( isset( $GLOBALS['__itsec_remote_ip'] ) && $use_cache ) {

	$ip = apply_filters( 'itsec-get-ip', false );

Here’s another plugin WP-PostRatings that correctly returns user IP.

### Function: Get IP Address
if ( ! function_exists( 'get_ipaddress' ) ) {
	function get_ipaddress() {
		foreach ( array( 'HTTP_CF_CONNECTING_IP', 'HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR' ) as $key ) {
			if ( array_key_exists( $key, $_SERVER ) === true ) {
				foreach ( explode( ',', $_SERVER[$key] ) as $ip ) {
					$ip = trim( $ip );
					if ( filter_var( $ip, FILTER_VALIDATE_IP ) !== false ) {
						return esc_attr( $ip );
					}
				}
			}
		}
	}
}

I have contacted you using contact button on your blog 3 days back. Not sure you got my message.

Let take this conversation to private please. Please contact me before I can provide you with any more information.
