Just a quick suggestion for your Super Testimonials Pro script – you might want to change the line 57 in tp-testimonials-pro.php file to use min.js version of that JS file instead of the normal one, as it’s coming up as one of the suggestions in web.dev pagespeed tests (to minify that file), since you already have the minified version of it included with the plugin:
 
wp_enqueue_script( ‘tps-super-pro-owl-carousel-js’, plugins_url( ‘frontend/js/owl.carousel.min.js’, __FILE__ ), array( ‘jquery’ ), ‘2.4’, true);
 
Cheers!
