We got the report this morning, and fixed it in latest v3.0.8.5 release. The WooCommerce is a different issue. Separate topic can help us get notified of the issues faster. The O_CRAWLER_MAP_TIMEOUT error will disappear after you refreshed the page. Its a potential one time error. It could happen bcos you are having cron running at the moment upgrade. This new setting is for the crawler cron.
