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' 
) );

I was crazy here because I couldn't solve a serious browser cache issue on my site. Due to a problem with the cache, my customers were unable to make any purchases at my store, as the products had color and others options and they did not load. It was not a question of style, but of functionality. I did everything possible, restarted the server, excluded plugins, I even changed the theme to see if it forced cleaning, but nothing resolved. This plugin saved me. Thank you very much for your work!!!

Thank you for this very helpful plugin. It works as expected and I use it on all of our development sites.

I'm glad I have found something like this, its not 100% what I was looking for since I would have preferred the query string to automatically update everytime a file has actually been changed. Hopefully we can see this in the future. It's a shame plugins like this have to exist, it should be part of WP core. Since its not though, I am very grateful for this plugin. EDIT: The Manual button does not seem to work if I disable automatic mode. -1 Star. EDIT: The Manuel button has been fixed. +1 Star.

FINALLY the mobile browsers are refreshing! This was driving me up the wall. I couldn't even debug my own designs in my mobile apps because of that pernicious caching. This plugin does the trick. I'm using Astra and Elementor, if that info is helpful to anyone. (Also, I tried Rebusted, but that had no effect.)
