I got Warning at backend after update to WordPress 5.3
Warning: Declaration of W3TC\DbCache_Wpdb::prepare($query, $args) should be compatible with wpdb::prepare($query, …$args) in /
xxx/ xxxx/public_html/wp-content/plugins/w3-total-cache/DbCache_Wpdb.php on line 8
When I disable Database Cache warning disappears.
