Hi I’m using autoptimize and wp fastest cache for optimizing my site. Our team used WP Total cache before but we decided to change to WP Fastest Cache for some reason. But still I only have a grade of F in GTMETRIX in Defer parsing of Javascript. Can you help me from this?

Hi There,

Please add the following code under functions.php file locates in your child theme:

if (!(is_admin() )) {
	function defer_parsing_of_js ( $url ) {
		if ( FALSE === strpos( $url, '.js' ) ) return $url;
		if ( strpos( $url, 'jquery.js' ) ) return $url;
		if ( strpos( $url, 'x-head.min.js' ) ) return $url;
		return "$url' defer='defer";
	}
	add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
}

Hope it helps 🙂
