 * Hello:
 * Pagespeed focus on block rendering… if using any optimizing plugins as autooptimize,
   may add recaptcha as whitelisted if you want it to run without problems…
 * So I needed to async or defer its load, excluding js from autooptimize as well..
 * Just edit functions.php
 * /************************************************************************
    /*
   AÑADIENDO ASYNC A RECAPTCHA PARA PAGESPEED /*************************************************************************
   [http://matthewhorne.me/defer-async-wordpress-scripts/](http://matthewhorne.me/defer-async-wordpress-scripts/)*************************************************************************/
   function add_async_attribute($tag, $handle) { if ( ‘google-recaptcha’ !== $handle)
   return $tag; return str_replace( ‘ src’, ‘ async=”async” src’, $tag ); } add_filter(‘
   script_loader_tag’, ‘add_async_attribute’, 10, 2); /************************************************************************/
 * that is all… script async load, and no rendering blocks..
 * Please developer, consider this.
 * Thanks.
