Hi there,
couple of common issues:
1. You will want to disable lazy loading on the Logo – to do that add this PHP snippet:
function rocket_lazyload_exclude_class( $attributes ) {
$attributes[] = 'class="is-logo-image"';
return $attributes;
}
add_filter( 'rocket_lazyload_excluded_attributes', 'rocket_lazyload_exclude_class' );
2. WP Rocket Critical CSS – unless you’re able to write your own critical CSS you should DISABLE this option. As this is a major cause of CLS.
