Remove ?Ver Querystring Parameter From Static Resources with WordPress

The following code example will remove all “?ver=” querystring parameters from static resources such as JS or CSS files, and may cause you issues with caching those.

Just place it in your theme’s functions.php and it’ll do:

function remove_ver_css_js( $src ) {
    if ( strpos( $src, 'ver=' ) )
        $src = remove_query_arg( 'ver', $src );
    return $src;
}
add_filter( 'style_loader_src', 'remove_ver_css_js', 9999 );
add_filter( 'script_loader_src', 'remove_ver_css_js', 9999 );
