Prevent Browser Caching


Are you a frontend developer? Do you want to clear browser cache for all users? Just activate this plugin and show your work!

Prevent Browser Caching allows you to update the assets version of all CSS and JS files automatically or manually in one click.

Now you can show the latest changes on the site without asking the client to clear the cache.

How it works?

Usually, WordPress loads assets using query param “ver” in the URL (e.g., style.css?ver=4.9.6). It allows browsers to cache these files until the parameter will not be updated.

To prevent caching of CSS and JS files, this plugin adds a unique number (e.g., 1526905286) to the “ver” parameter (e.g., style.css?ver= for all links, loaded using wp_enqueue_style and wp_enqueue_script functions.

For developers

By default, this plugin updates all assets files every time a user loads a page and adds options in the admin panel (Settings -> Prevent Browser Caching) which allows you to configure updating of these files.

But you can also set the version of CSS and JS files programmatically.

Just insert this code in functions.php file of your theme and change the value of assets_version when you need to update assets:

prevent_browser_caching( array( 
    'assets_version' => '123' 
) );



From WordPress dashboard

  1. Visit “Plugins > Add New”.
  2. Search for “Prevent Browser Caching”.
  3. Install and activate Prevent Browser Caching plugin.

From site

  1. Download Prevent Browser Caching plugin.
  2. Upload the “prevent-browser-caching” directory to your “/wp-content/plugins/” directory.
  3. Activate Prevent Browser Caching on your Plugins page.

I found this plugin while searching for a way to prevent CSS files from caching while working with a particularly annoying theme (A****). This works perfectly and I will use it on every website I'm developing from this point forwards. Thank you!

Works very well when you have a very heavily cached website that is typically frequented by the same users and you have to force a change, this does it so simply right out of the box. Great work! **EDIT** Found that this plugin doesn't play nicely with WooCommerce, so if you plan on using it on your store, make sure to do some sandbox testing to ensure that you are able to complete transactions. We had an issue on a site where it was complaining about the payment type and displaying errors. Once disabled, the site was fine.
