Hide Your WordPress Version Number more about your site than you may think. Every time WordPress makes updates or fixes bugs, the changes are notated in detailed reports. This means the general public knows which security bugs affect which version. Specifically, this means hackers know exactly what kind of attack to use on your website. This is why it’s very important to hide your version number. Any hacker can find your WordPress version by simply viewing the source code of your site in any web browser.
You may be wondering, should I just update my site automatically? Yes, updating your site whenever prompted (or even automatically) is a way to avoid possible security breaches. But, for one reason or another, updates may be skipped or ignored altogether. Either way, it’s best to hide your version number.
How To Hide Your WordPress Version Number
Hiding your WordPress version number can enhance your website’s security by making it harder for attackers to exploit known vulnerabilities associated with specific WordPress versions. Here are several methods to hide your WordPress version number:
1. Removing the Version Number from the Head Section
WordPress adds the version number to the HTML <head> section of your site. You can remove it by adding the following code to your theme’s functions.php file:
remove_action('wp_head', 'wp_generator');
2. Removing the Version Number from RSS Feeds
WordPress also adds the version number to RSS feeds. You can remove it by adding the following code to your theme’s functions.php file:
function remove_wp_version_rss() {
return '';
}
add_filter('the_generator', 'remove_wp_version_rss');
3. Hiding the Version Number in Enqueued Scripts and Styles
Plugins and themes can add the version number to their scripts and styles. To remove it, add the following code to your theme’s functions.php file:
function remove_version_from_scripts_styles($src) {
if (strpos($src, 'ver='))
$src = remove_query_arg('ver', $src);
return $src;
}
add_filter('style_loader_src', 'remove_version_from_scripts_styles', 9999);
add_filter('script_loader_src', 'remove_version_from_scripts_styles', 9999);
4. Using a Security Plugin
Many WordPress security plugins offer the ability to hide the version number as part of their feature set. Some popular security plugins include:
- WP Security Safe
- Log into your WordPress Dashboard
- Click the WP Security Safe link in the left side panel
- Choose the Privacy tab
- Check the box for Hide WordPress Version Publicly
- Click Save Settings at the bottom of the plugin menu
These plugins often provide additional security features, making them a good choice for comprehensive site protection.
5. Editing the Meta Tag in wp-includes/general-template.php
Although not recommended because it involves modifying core files, you can manually edit the wp-includes/general-template.php file. However, this change will be overwritten when you update WordPress.
To do this, find the following line:
echo '<meta name="generator" content="WordPress ' . get_bloginfo('version') . '" />' . "\n";
Comment it out or remove it:
// echo '<meta name="generator" content="WordPress ' . get_bloginfo('version') . '" />' . "\n";
6. Custom Meta Tag with Hook
Alternatively, you can use a hook to remove and then add your own meta tag without the version number. Add the following code to your theme’s functions.php file:
function remove_wp_version_meta_tag() {
remove_action('wp_head', 'wp_generator');
}
add_action('init', 'remove_wp_version_meta_tag');
By using these methods, you can effectively hide the WordPress version number and improve the security of your website.
