Delete not working

Hi, The plugin does´nt delete correctly, not only because database prefix should be added but also because the query is not concatenated, so only executes the last query. $queries = $results = array(); $queries[] = “DELETE FROM {$wpdb->prefix}woocommerce_order_itemmeta;”; $queries[] = “DELETE FROM {$wpdb->prefix}woocommerce_order_items;”; $queries[] = “DELETE FROM {$wpdb->prefix}posts WHERE post_type = ‘shop_order’;”; $queries[] = “DELETE FROM {$wpdb->prefix}posts WHERE post_type = ‘mail-debug’;”; foreach( $queries as $query ) { $results[] = $wpdb->query( $query ); } Error treatment should be implemented later.
