Sneakily Hide WP Versions


Hides the WordPress version everywhere it’s displayed, including feed generator tags, static asset URLs, load-styles.php and load-scripts.php, and in /wp-admin/install.php and /wp-admin/upgrade.php. Some plugins hide the WordPress version, but not everywhere, and that’s as good as not hiding it at all. This plugin hides all occurrences of the WordPress core version.

This version hiding doesn’t break the cache-busting that WordPress does using the version number in static assets URLs.


  • Hides WordPress version in static asset (CSS, JS) URLs
  • Hides WP version in feed XML
  • Hides WP version in admin pages and static asset loaders (load-scripts, load-styles)
  • Doesn’t break the cache-busting on WordPress core assets when WordPress upgrades

Multisite is not supported yet, but support is intended for a future release.

Supported Platforms

This plugin works with WordPress 5 and PHP 7+. It’s best to use the Apache web server, with .htaccess support. Nginx works ok too, but you need to update the web server configuration manually. Microsoft IIS is not officially supported, for now.


  • WordPress 5 or above
  • PHP 7 or above
  • Apache or Nginx web servers (Apache 2.4.10 and above, or Nginx 1.11.6 and above)
  • If using Apache, either .htaccess support enabled AND permalinks enabled *, or the ability to edit the web server configuration and restart the web server
  • If using Nginx, the ability to edit the web server configuration and restart the web server


Support isn’t currently available, but if you’ve followed instructions and read the FAQ and it still isn’t working on your platform, bug reports are appreciated, either by using the forum or by direct contact. If there’s a bug it will probably be fixed in a short while.


  1. Ensure your setup meets the Requirements, above
  2. Install from the Plugin Directory or manually download and unpack the zip file
  3. Activate plugin using WordPress admin
  4. Depending on your configuration, you might need to update the web server configuration (.htaccess / Apache config / nginx config) and restart your web server


Why bother hiding the WordPress version?

If somebody wants to hack your site, knowing the WordPress version you’re running saves a lot of time. This plugin denies potential attackers that information.

Isn’t this Security Through Obscurity?

First: a few comments about security through obscurity. As the WordPress Hardening guide points out, this is correctly, usually seen as a security anti-feature: if something is secure, it shouldn’t matter what an attacker knows about it. This principle works well in certain situations: cryptography, open source code, anything where the implementation is public. However, it doesn’t work well in situations where implementations are not public: for example, the behind-the-scenes implementation, infrastructure and source code of your own website. Unless you intend to expose all that for public review – something true in a very limited number of cases – then “what configuration your WordPress site has” isn’t something that should be publicly knowable.

Given your website configuration is being kept private already, it only helps an attacker, and potentially hurts you, to expose information that doesn’t benefit your business. Again, the WordPress Hardening Guide says “However, there are areas in WordPress where obscuring information might help with security.” Obscuring the WordPress version number(s) is arguably one of those areas: one of the most common types of attacks against WordPress is “sending specially crafted HTTP requests [that exploit] … specific vulnerabilities.” Often these specific vulnerabilities rely on knowing the WordPress version, or the version of other plugins or themes. And information gathering, finding out the details of target websites and systems in advance of an attack, is part of penetration testing methodology for a reason: actual attackers use it. You don’t want them using it against your site.

Another way to look at this is: what is your threat model? What threats to your website and business are realistic and worth defending against? Vulnerabilities in WordPress core are threats worth taking seriously, because even if they’re fixed in a later release, there’s still a window of opportunity for attackers, and they’ll want to know if your site is up to date – by checking the WordPress version.

So is this security through obscurity? No. The security of your WordPress site comes from what’s elsewhere: keep your core and plugins up to date, using security plugins, using a Web Application Firewall, and all the other security best practices.

Our plugin hides information, making it unavailable to attackers, and making their life more difficult: an important part of having a secure website.

Does Hide WP Version work correctly when WordPress updates to a new version?


Why do my CSS and Javascript URLs still have a version at the end?

Hide WP Version generates a random number and uses that as a fake WordPress version number. This is because WordPress uses the version number on the end of URLs for “cache busting” – forcing browsers to load a new version of a file. Generating and using a fake version number hides the real version number without breaking this aspect of WordPress’s functionality.

Can I change the fake version number?

Yes, but not to anything you choose. To update the fake version number, log in to your WordPress site as an Administrator and select Ruminative WP > Hide WP Version from the menu. There’s a button to bump the fake version.

Can I use a specific value for the fake version number?

No, because what happens when WordPress core is upgraded to a new version and this value needs to change? For simple values like “1” this could work, but then why bother specifying a custom value? If it’s not a simple value like “1”, but something like “pomegranate”, what should the new value be? You’d need to update the value manually every time WordPress core updates, and that’s annoying. Let the plugin handle this.

Is this much code really necessary to hide WordPress versions? Isn’t it excessive?

Respectively – yes, it’s necessary, because WordPress attaches extra meaning to version numbers, in its handling of static assets; and “it depends,” if you want to secure your site as much as possible, then it might not be excessive.

Does this block the sending of my version to

No, currently this isn’t blocked, because knowing your WP version isn’t generally a security risk.
