Remove file version strings from CSS and JS links

By default .css and .js files used in WordPress themes and plugins will add a version number using ?ver=

To disable this add the following inside your theme functions.php file or as a new plugin:

//Remove version strings from CSS and JS links

add_filter( 'style_loader_src', 'wpxss_remove_version' );
add_filter( 'script_loader_src', 'wpxss_remove_version' );

function wpxss_remove_version( $url )
{
    return remove_query_arg( 'ver', $url );
}
