Errors in Moz, Raven Tools and Webmaster tools skyrocketed across all levels in one week between audits. Site is large with over 450 pages and a separate blog running on wordpress. Wordpress posts have disappeared completely from the site and wordpress. Main site pages have also disappeared. No sign of hacking. Duplicate content has exploded in errors. I work in house, everyone here from developers to co-founder is completely baffled. Any one have any ideas?
