Saves you from asking “have you emptied your cache?”.
Forked and updated for todays WordPress and PHP from the original plugin by Paul Clark.
Features
<ul>
<li>Safe to leave running on live sites.</li>
<li>Only refreshes browser cache for a file if it has been modified.</li>
<li>Resolves Content Delivery Network (CDN) issues. No need to purge CDN cache.</li>
<li>Multisite compatible.</li>
<li>“Just works” – no configuration necessary.</li>
</ul>
Requirements
Requires scripts use any of the below functions to load. Almost all files meet these requirements. The only case it doesn’t account for is when URLs are hard-coded. This shouldn’t ever be done, since it can break sites for other reasons.
<ul>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_style" rel="nofollow ugc">wp_enqueue_style</a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_script" rel="nofollow ugc">wp_enqueue_script</a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/get_stylesheet_uri" rel="nofollow ugc">get_stylesheet_uri</a></li>
</ul>

reBusted!

I always have one or two clients where "its still not working for us"

This is the plugin that solves that. 

Recommend developers/agencies everywhere install this and save them and their clients a bundle of time. 

Thanks for keeping this alive after the last Busted version went AWOL. 

Thanks for keeping this alive


This is a great tool for advanced developer. It saves you from manually versioning your css/scripts or devising your own versioning solutions based on system time which would reload css/js every time, slowing a page load. This ensures only changed styles/scripts are reloaded. Five stars!


A must

Force browsers to load the most recent file if modified.
