In some cases autoptimize JS scripts will be cached in Google and return 404 results if the autoptimize cache has been cleared. To get around that problem this piece of code returns a HTTP 410 Gone for all those scripts that return a 404 because they have been cleared from the Autoptimize cache.
<?php
add_action( 'template_redirect', 'yanco_404_redirect_to_410_for_autoptimize' );
function yanco_404_redirect_to_410_for_autoptimize() {
if( is_404() ) {
$search = 'cache/autoptimize/js/autoptimize_';
if( strpos( $_SERVER['REQUEST_URI'], $search ) !== false ) {
wp_redirect( $_SERVER['REQUEST_URI'], 410 );
exit;

Apparently SearchWP/Relevanss and Elementor doesn't play well together with Elementor, Searches and post grid. This is the outline of handling searching in post_meta.
<?php
// Modify the fields to search in
add_action( 'elementor/query/searched_query', function( $query ) {
$s = get_search_query();
if ( is_search() ) {
$query->set( 'post_type', 'leverandor' );
if( strlen($s) >= 3 ) {
