Autover plugin will automatically version your CSS and JS files. This is especially useful when using a Content Distribution Network (CDN) for delivering static files like CSS and JavaScripts. The plugin appends to the resource URL a numeric version number generated by the filemtime() PHP function (e.g. style.css?ver=1359464809). This means the version number will be updated every time the CSS or JS file is being saved.
IMPORTANT: this plugin only works with CSS and JS files that are enqueued using the standard WordPress functions <a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_style" title="wp_enqueue_style" rel="nofollow ugc">wp_enqueue_style</a> and <a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_script" title="wp_enqueue_script" rel="nofollow ugc">wp_enqueue_script</a> and/or <a href="https://codex.wordpress.org/Plugin_API/Action_Reference/admin_enqueue_style" rel="nofollow ugc">admin_enqueue_style</a>, <a href="https://codex.wordpress.org/Plugin_API/Action_Reference/admin_enqueue_scripts" rel="nofollow ugc">admin_enqueue_script</a>.
