WordPress xml sitemap noindex errors – Google Search Console (aka Webmaster Tools)

If you notice Google Webmaster tools console flagging up the following…
Error – Submitted URL marked ‘noindex’ for http://site.com/sitemap.html

You can easily prevent these HTML files being created by the “XML Sitemap Generator for WordPress” plugin.

This is NOT in your site’s robots.txt file but instead it’s a meta tag in all html sitemap pages generated by the plugin.
The only page Google needs is the sitemap.xml file these extra html files aren’t needed.

  1. Login to wordpress (ofc)
  2. Go to settings > XML-sitemap
  3. Find and un-tick “Include sitemap in HTML format”
  4. Make sure to apply the change by scrolling to the bottom of page and click [Update options]

Single PHP error page to handle all response headers / errors

There might be an easier way of doing this but i’ve been working on a project which needed the following which i have done as a simple single php page and thought i’d share it in case anyone wants to do the same thing.

  1. Error page generated by dynamic pages
    (using any code; 403, 404 etc)
  2. Error page to handle genuine errors
    (404 ‘Not Found’, 403 ‘Forbidden’ etc)
  3. Forbid visitors from visiting sensitive areas/directories
    also returning 403 ‘forbidden’ header.
    (e.g. /images, /css /javascript, /ajax etc)

Download all these files: http-error-code.zip

instructions for use are commented within the error.php code but in summary:

You need to create a .htaccess entry for each error code:

Code for .htaccess:


ErrorDocument 403 /error/error.php
ErrorDocument 404 /error/error.php

For forbidden folders just add this code into a file called index.php then put this file into the folder that you want to forbid directory listing for:

Code for index.php:

<?php
// Set response code
$error = 403; //Forbidden
// include the error page (
include ($_SERVER['DOCUMENT_ROOT'].'/error/error.php'); // assuming "/error/error.php" is the location/name of this file
// stop processing the current page
exit();
?>

Save this code to a file called error.php and save to yourdomain.com/errors/error.php

Code for error.php:

<?php
/*

To generate response from another page, as a result of incorrect database query or invalid content etc just add this code:
(make sure no page output has been generated before this include)

<?php
// Set response code
$error = 403; //Forbidden
// include the error page (
include ($_SERVER['DOCUMENT_ROOT'].'/error/error.php'); // assuming "/error/error.php" is the location/name of this file
// stop processing the current page
exit();
?>

-------------------------------------------------------
TIP:
-------------------------------------------------------
Hide the default directory listing for a folder
e.g. /images, /css, /java etc.

1. create a blank file called index.php
2. paste the php code above into the file
3. place it inside the folder

// THE CODE...
// ------------------------------

// if the error code has been set by referring page:
if ($error <> ""){
// Use the error code from referring page
$code = $error;
} else {
// Use the error code from server
$code = $_SERVER['REDIRECT_STATUS'];
}

// set $path variable to the requested path/uri
$path = $_SERVER['REQUEST_URI'];

// Create array with error codes and messages
// You must add a line to .htaccess for each code used here.
// e.g.
// ErrorDocument 403 /error/error.php
// ErrorDocument 404 /error/error.php
// etc...
// (assuming /error/error.php is the location/name of this file)

// Customise the page to be displayed below...

// -------------------------------------------------------
// You can use the variables $title and $message in the page
// -------------------------------------------------------
// e.g.
//        echo "<h2>".$title."</h2><p>".$message."</p>";
// -------------------------------------------------------

// -------------------------------------------------------
// !! IMPORTANT !!
// -------------------------------------------------------
// if you want to include a header / footer in the page displayed
// make sure you use $_SERVER['DOCUMENT_ROOT'] in your include code
// e.g.
//         include($_SERVER['DOCUMENT_ROOT']."/inc/header.php");
//
// this ensures the header/footer path is always correct
// e.g.
//        actual path of header.php = "http://www.domain.com/inc/header.php"
//         if path/uri is "domain.com/foo/" header path would incorrectly become "domain.com/foo/inc/header.php"
//        if path/uri is "domain.com/foo/bar/" header path would incorrectly become "domain.com/foo/bar/inc/header.php"
