  add_filter('autoptimize_html_after_minify', function($content) {       $site_url = 'https://YOUR_SITE_LINK_HERE';//do not set slash on the end       $content = str_replace("", ' ', $content);     $content = str_replace('', ' ', $content);       $content = str_replace(" ", ' ', $content);     $content = str_replace(' ', ' ', $content);     $content = str_replace("rel='stylesheet preload' as='style'", "rel='stylesheet preload'", $content);     $content = str_replace('rel="stylesheet preload" as="style"', 'rel="stylesheet preload"', $content);       $content = str_replace('@font-face {font-display: swap; ', '@font-face {font-display: swap; font-display: swap;', $content);     $content = str_replace('@font-face {font-display: swap; ', '@font-face {font-display: swap; font-display: swap;', $content);     $content = str_replace("<img", "<img loading='lazy'", $content);       $content = str_replace($site_url . '/wp-includes/js', '/wp-includes/js', $content);     $content = str_replace($site_url . '/wp-content/cache/autoptimize', '/wp-content/cache/autoptimize', $content);     $content = str_replace($site_url . '/wp-content/themes/', '/wp-content/themes/', $content);     $content = str_replace($site_url . '/wp-content/uploads/', '/wp-content/uploads/', $content);     $content = str_replace($site_url . '/wp-content/plugins/', '/wp-content/plugins/', $content);       return $content; }, 9999, 1);

• Also it is possible to optimize jquery.js which is excluded in Autoptimize, but this way not always work, so check your site functionality after next:
  • in your site current wp theme file functions.php add next code:
    
    //exlude jquery to print it in the header by file_get_contents add_action('wp_enqueue_scripts', function () { wp_deregister_script('jquery'); });

    //exlude jquery to print it in the header by file_get_contents add_action('wp_enqueue_scripts', function () {     wp_deregister_script('jquery'); });

  • in your site current wp theme file functions.php add next code before <?php wp_head(); ?>:
    
    <script> <?php echo file_get_contents(ABSPATH . WPINC . '/js/jquery/jquery.js'); ?> </script>

    <script>   <?php echo file_get_contents(ABSPATH . WPINC . '/js/jquery/jquery.js'); ?> </script>
